What’s Trending for Prom 2027 Dresses?

Prom 2027 is all about the dress details. Pearls, strategically sprinkled along necklines and corset boning or splashed across an entire gown. Corsets show their structure with visible boning, and sculpted Basque waistlines are in. Tiered ruffles turn up the volume, stacking floaty layers into full skirts made to move. Florals bloom big, bringing fresh color and romance to everything from princess ball gowns to sleek fitted looks. And rich, textured fabrics add dimension with woven florals, metallic brocades and tone-on-tone patterns.

Designed for Curves from the Start

When coming up with a new Prom designs we always ask ourselves, "What kind of looks, styles, and colors are straight-sized girls looking for?" The looks they love are exactly what we set out to create for plus size girls, because every body deserves to have the incredible experience of finding a Prom dress that makes them feel beautiful, comfortable, and confident.

At Sydney’s Closet, designing for curves starts with fashion. Is the look on trend? Who’s wearing that dress —the Prom Princess, the Sophisticate, the Rebel, the Shining Star or the Hollywood Diva? What will make her fall in love with it? And what story will her dress tell when she walks into Prom?

Then we engineer the fit. A design has to work across our plus size range without losing what made it fabulous in the first place. We evaluate how the dress will look, feel, and fit on different body shapes and sizes.

As sizes increase, the design experts at Sydney’s Closet look at more than measurements. They ask:

• Can the proportions and style lines stay true to the original design? 
• Does the length need adjusting?
• Do the straps need to be wider to be bra-friendly?
• Will lace appliqués, pearls or a drizzle of sequins still land in just the right places?
• Sometimes no pattern pieces need to change beyond grading. Sometimes one does.
• Sometimes five or more need to be reworked until we approve the sample.
• That’s the difference between making a Prom dress in a larger size and designing a Prom dress for curves from the start.

Our size chart is specific to us, so make sure you check it. Unsure how to measure? Watch our easy-to-follow How to Measure video. Still not sure which size to order? You can always call, email, or message us on social media. Our expert stylists would love to help you find the best fit for your curves. Find out more about how to contact us here.

Shopping in a store? Ask to be measured and try on different sizes and silhouettes. Pay attention to how the dress fits and feels when you sit, walk and move. A knowledgeable stylist can help you find the right size and determine whether alterations can make the fit even better.

And don’t be surprised if your Prom dress needs alterations. A hem, strap adjustment or other small change can turn a great fit into your perfect fit.

Head-to-Toe Prom Glamour

Your Prom shoes are part of the look, so have fun finishing your style from head to toe. Love heels? Go for them—but remember to break them in before the big night. Prefer flats? They can look just as fabulous, especially with a little glitter. Sparkly sneakers or sequin tennis shoes let the crowd know you came ready to dance.

Whatever you choose, make sure your shoes are comfortable enough for a long night. And decide on them before your dress is hemmed. A long formal gown is designed with extra length for heels, so if you’re wearing flats or sneakers, chances are you’ll need the hem shortened. Wear your Prom shoes to your alteration appointment so your dress hits just the right length.

Add Your Finishing Touches

Let your Prom dress lead the way. Wearing a gown loaded with pearls, sequins or sparkle? Keep your jewelry simple and let the dress do the talking. Choose a sleek, understated style? Have fun adding statement earrings, a necklace or a fabulous evening purse. Think about your neckline when choosing jewelry so the pieces complement—not compete with—your dress. Make the dress your main character. The final details are where you really get to have fun, leave your hair down to compliment your strapless look. match your lips to your dress, bring the pearl details from your dress into your nails. It's time to make the look completely yours.
