Mia Thermopolis’s princess look is one of the few costumes people recognise from the accessories alone: a white formal dress, opera gloves, a tiara, dark sunglasses and big retro headphones. That’s good news, because it means the dress itself can be almost anything white that fits you well. I’ve put together twenty versions below, from a close copy of the strapless ball gown to a cotton sundress for a daytime party, and for each one I’ve noted what tends to go wrong and who it suits. Most of them are built for themed birthdays, bachelorette weekends and photo shoots, so comfort over a long evening counts as much as the look.

Tiara, Gloves and Headphones: Getting Them to Stay Put
Every outfit below shares the same accessory kit, and that kit is what causes most of the trouble over an evening. Sort it out once and you can wear any of the dresses with confidence.
The tiara
A tiara slides on smooth, freshly washed hair. I lightly backcomb a small section where the comb sits, slide the tiara in, then cross two bobby pins through the side loops or behind the comb so it can’t rock forward. Choose a lightweight one; heavy metal tiaras cause headaches after a couple of hours.
The headphones
Over-ear headphones press on the tiara and the top of an updo. Place the band behind the tiara, not on it, and wear them round your neck for most of the event, putting them on for photos. Lightweight costume or toy headphones are kinder to a hairstyle than real studio ones.
The gloves
Opera gloves should reach above the elbow, and they’re hard to take off quickly. Roll them down from the top for eating and drinking rather than pulling at the fingertips, which stretches the seams. Rings go over the gloves, never under.
1. Princess Diaries White Strapless Ball Gown

This is the closest copy of Mia’s transformation, so the details have to be right. A fitted strapless bodice with light beading and a floor-length skirt that flares softly, not a huge crinoline. The bodice is where strapless gowns fail; if it doesn’t have boning and a grip strip at the top edge, you’ll be hitching it all night, especially with gloves on, which make tugging awkward. Add elbow-length satin gloves, a small crystal tiara, wraparound sunglasses, silver over-ear headphones and white pointed pumps. A smooth bun or twist leaves the neckline clear, and red lipstick with small crystal earrings finishes it. On a petite frame I’d keep the skirt narrower; taller wearers can carry a wider hem.
2. Princess Diaries White Satin Midi Dress

Satin at midi length is the version I’d pick for anyone who wants to dance. It sits between knee and ankle, so there’s nothing to trip over, and a strapless or softly draped bodice still nods to the original. Satin does show every crease and line, so look at it after sitting for ten minutes in the fitting room before deciding. White slingbacks, short satin gloves, a delicate tiara, black sunglasses and padded black headphones complete the reference. A silver clutch is practical. Keep the hair in a low bun with a neat side part and pair red lipstick with softly defined eyes so the face isn’t all one strong note. It’s also the one you’re most likely to wear again.
3. Princess Diaries White Tulle Mini Dress

Want something playful that still reads royal? A strapless white tulle mini with a fitted bodice and a few soft layers does it. Watch the volume: stiff, heavily layered tulle at mini length sticks out like a tutu, while moderate layers move nicely. White block heels or crystal Mary Janes let you stand for hours. Wrist-length gloves, a petite tiara, oval sunglasses and over-ear headphones carry the theme, and a tiny silver shoulder bag holds a lip stain. I’d use a red stain here instead of heavy lipstick, since it suits the younger feel and survives drinks. Sheer white tights add coverage if you want it.
4. Princess Diaries White Modest Maxi Dress

You don’t need bare shoulders to get the princess effect. A floor-length white dress with a high bateau neck, a fitted waist and a flowing chiffon skirt, plus flutter or elbow sleeves, gives the same impression. This one works well for anyone who prefers conservative clothing. White chiffon is often sheer, so insist on an opaque lining and check the skirt for any slit that opens when you walk. With a high neckline, I skip the necklace and go for small pearl studs. White kitten heels, satin gloves, a narrow tiara, dark sunglasses, black headphones, a smooth low bun and red lipstick with rosy blush complete it.
5. Princess Diaries White Plus Size A-Line Dress

For plus-size figures, I’d build the look on a structured A-line with real support: firm straps, a shaped waist and a skirt that moves freely over the hips. Princess seams or soft draping at the waist give definition without squeezing. A sweetheart or square neckline leaves room for a fine crystal necklace. Gloves are where people get caught out; standard opera gloves can be tight on the upper arm, so measure and look for stretch satin or sized gloves. Low white block heels, a sparkling tiara, black sunglasses and padded headphones complete it, with a sleek bun, red lipstick and luminous skin. Comfortable pieces are what let you look confident all night.
6. Princess Diaries White Long Sleeve Lace Dress

Lace with long sleeves makes this a cooler-weather version with a vintage softness. Choose a white floor-length dress with a lined bodice, sheer lace sleeves and a flared skirt, and keep the lace pattern simple, because busy lace competes with the tiara and headphones that make the costume readable. Gloves can go; the sleeves already add texture, and gloves under lace cuffs bunch at the wrist. White pointed flats or low heels, a small crystal tiara, black sunglasses and over-ear headphones carry the theme. A white satin clutch, a low chignon and classic red lipstick finish it for an indoor party in autumn or winter.
7. Princess Diaries White Corset Midi Dress

A corset bodice on a midi skirt gives the outfit shape and a more fashion-led edge. The structure should hold you, not squeeze; sit, breathe in fully and reach for something across a table before you buy. If any of that pinches, go up a size and have the waist taken in. Full skirt below the knee, white ankle-strap heels, satin opera gloves, a crystal tiara, black sunglasses and oversized headphones keep it on theme. A small silver top-handle bag, a French twist or bun, red lipstick and a little winged liner finish it. The boning gives definition on straight, curvy and hourglass shapes alike.
8. Princess Diaries White Off Shoulder Dress

Off-the-shoulder is a softer neckline than the original strapless gown, and in my experience it stays put better, because the sleeves anchor it across the upper arm. A tea-length or floor-length dress with a fitted waist and draped sleeves suits it. Fashion tape inside the top edge is still worth applying. Keep the hair up so the shoulders show and the headphones don’t flatten loose strands. Crystal tiara, satin gloves, wraparound sunglasses, black headphones, white pointed pumps and a silver clutch carry the theme, with pearl drops and red lipstick. It suits an elegant themed party or bright photo session.
9. Princess Diaries White Slip Dress

A lined satin slip dress gives the costume an early-2000s feel and comes together from pieces many people already own. Midi or ankle length with adjustable straps is easiest. Unlined slip dresses cling and show every seam underneath, so check the lining first. A fitted white shrug adds shoulder coverage. White kitten-heel sandals, short satin gloves, a slim tiara, black sunglasses, chunky headphones and a little rhinestone shoulder bag finish it. A slightly undone bun keeps it young. Red lipstick and fresh skin are the only makeup it needs, which makes it a quick option for a casual themed night.
10. Princess Diaries White Puff Sleeve Dress

Soft puff sleeves give Mia’s look a storybook touch and hold the neckline in place, so there’s no strapless anxiety. Pick a white midi or maxi with short puffs, a fitted waist and a gently flared skirt. The sleeves need a lining or a bit of tulle inside to keep their shape through an evening; thin cotton puffs go flat. A square neckline suits a small crystal pendant. White Mary Jane heels, wrist gloves, a petite tiara, black sunglasses, over-ear headphones and a silver box clutch complete it. I’d keep the hair to a braided bun or smooth low updo, because big hair plus big sleeves gets crowded fast.
11. Princess Diaries White Sequin Mini Dress

For a party version, a white sequin mini with a clean fitted shape works well. Small or matte sequins sit back and let the tiara do its job; oversized paillettes compete with it. Think about how long you’ll stand: platforms look great for photos, low block pumps last longer. Elbow gloves, black sunglasses, silver headphones and a crystal crown carry the theme, with a plain white clutch to calm the shimmer. A high bun and red lipstick finish it. Check the inside of the arms too, since sequins at the side seams rub. Sheer tights or a long-sleeve version add coverage if you want it.
12. Princess Diaries White Fit And Flare Dress

Fit-and-flare is the simplest foundation for a wearable Mia costume. A knee-length or midi with a defined waist and enough skirt to swing suits most figures, especially with a sleeveless boat neck or modest sweetheart. If the waist isn’t quite defined enough, a slim silver belt fixes it cheaply. White pumps, short gloves, black sunglasses, over-ear headphones and a delicate tiara complete the theme, with a structured white bag. Smooth bun, side part, red lipstick and light blush. It’s comfortable for a long event, and most of it can be pulled from an existing wardrobe.
13. Princess Diaries White High Low Dress

High-low hems give you a gown at the back and freedom at the front, which makes them practical for dancing. The front should land around the knee and the back near the ankle or floor. Your shoes are fully on show, so choose polished white pointed pumps rather than whatever is comfortable. Keep the bodice fitted and simple so the accessories read clearly: satin gloves, crystal tiara, black sunglasses and headphones, a small silver clutch and minimal jewelry. A sleek bun and bold red lipstick finish it. Long back hems collect dirt outdoors, so this one is better for indoor venues.
14. Princess Diaries White Square Neck Dress

A square neckline frames the face and feels modern. Wide straps are the real advantage here: they cover a regular bra and hold the bodice up, which avoids the fit issues strapless styles bring. Choose a midi or full-length dress with a fitted waist and A-line skirt, and check that the corners of the neckline lie flat when you lean forward. White slingbacks, elbow gloves, a slim crystal tiara, black sunglasses and retro headphones keep it on theme, with pearl studs and a small silver bag. A smooth low bun and red lipstick finish it.
15. Princess Diaries White Halter Dress

A halter shows off the shoulders and needs no necklace, so I’d go straight to small crystal earrings. Choose a midi or maxi with a secure high neck, fitted waist and flowing skirt. Raise your arms when trying it on; if the halter strap slides toward your throat, it needs shortening. Hair goes in a high bun, partly to show the neckline and partly because loose strands tangle in the headphone band. White heeled sandals, satin wrist gloves, a sparkling tiara, dark sunglasses, silver or black headphones, a compact clutch, red lipstick and a little highlight finish it. It’s the warm-weather pick of the list.
16. Princess Diaries White Babydoll Dress

A white babydoll dress is the most comfortable take on the costume: shaped upper bodice, raised waist and a loosely gathered skirt with nothing pressing on the middle. Short flutter sleeves add coverage without weight. White ballet flats or low Mary Jane heels keep it easy for a long party. Short satin gloves, black sunglasses, over-ear headphones, a small tiara and a silver mini bag complete the reference. A soft high bun and red lipstick with otherwise minimal makeup suit the playful shape. Add sheer white tights if the short hem feels too short once you sit down.
17. Princess Diaries White Empire Waist Gown

An empire waist starts the skirt just under the bust, which gives a long line and room through the middle. It’s comfortable for apple shapes, for anyone pregnant and for anyone who dislikes waist pressure. Choose white chiffon with a fitted upper bodice and supportive straps, and keep any crystal trim subtle. Chiffon hems at full length catch on heels, so have the hem set with your shoes on. White low heels, elbow gloves, a delicate tiara, black sunglasses, classic headphones and a satin drawstring bag or silver clutch complete it, with a smooth low bun and red lipstick.
18. Princess Diaries White Blazer Dress

The blazer dress is the least literal idea here, and the accessories do all the work of making it Mia. A double-breasted mini or knee-length style with a defined waist reads sharp; if the neckline is low, wear a white camisole underneath. The shoulder seam has to sit on your shoulder, or the whole thing looks borrowed. White pointed pumps, short satin gloves, a slim tiara, black sunglasses, oversized headphones, a structured silver bag, a sleek bun or ponytail, red lipstick and crystal earrings carry the theme. The real advantage is that the dress goes straight back into your wardrobe afterwards.
19. Princess Diaries White Casual Sundress

A simple white sundress is the budget version, and honestly one of the most fun for a daytime group outing. Knee-length or midi cotton with supportive straps, a fitted waist and a light flare is enough. Eyelet, poplin or linen blends add texture. White sneakers or low sandals keep you moving, and a small tiara, black sunglasses, chunky headphones and optional short gloves make it Mia. A silver crossbody bag beats a clutch when you need your hands free. Casual bun, red lip tint. Check thin cotton against the light for transparency before the day.
20. Princess Diaries White Beaded Formal Gown

A beaded formal gown is the most luxurious version, and the one where weight matters. Heavy beading drags the bodice down over an evening, so lift the dress and feel it before buying, and look for fine, lightweight crystal work concentrated at the bodice, waist or neckline. Keep the skirt smooth so the beadwork stands alone. White satin pumps, long opera gloves, a crystal tiara, black sunglasses, over-ear headphones, a silver evening clutch and small drops complete it. A structured updo and red lipstick with defined lashes suit formal photos. Get the hem tailored to your shoes so the gown moves cleanly.
Turning the Look Into a Bachelorette or Shower Theme
A Princess Diaries theme works especially well for a bride’s party, because the white dress belongs to her and the accessories can be shared with everyone else.
- Put the bride in the most formal white version, such as the ball gown, satin midi or beaded gown, and let guests wear any colour with the same sunglasses, headphones and small tiaras so the photos still look like a set.
- Order tiaras and gloves in bulk well ahead; costume sizes vary and you’ll want time to swap ones that don’t fit.
- Plan for the venue. Long gowns and heels suit a dinner; sundresses, sneakers and the fit-and-flare suit a daytime crawl.
- At a wedding where you are a guest, leave the white dress at home and keep the theme for the party before it.
Red lipstick is the one makeup detail everyone shares, and it’s the first thing to wear off. A long-wear liquid lip with a thin layer of powder pressed through tissue holds up through drinks far better than a creamy bullet, and a small lip pencil in the bag covers touch-ups.
The Tiara and Headphones Make It, the Dress Lets You Move
Mia’s look adapts to almost any body, budget or occasion because the recognisable parts are the accessories. The strapless ball gown is the closest copy; satin midis, lace, puff sleeves and sundresses are practical alternatives. Get the white shoes, gloves, tiara, sunglasses, headphones, updo and red lip right, then choose a dress that stays secure when you sit and dance. That’s the version you’ll enjoy wearing all night.
