What's Your Prom Personality?
No matter what your fashion look, Sydney’s Closet has 2021's trendy plus size prom dress of your dreams. With so many choices, where can you start narrowing down the options?

Begin by determining which is the best dress for you to wear on the biggest night of 2021. To do that, you must first know your Prom personality and stay true to you. (Don’t worry, we pack our Closet with drop-dead gorgeous gowns to fit any Prom personality!)

Class Clown 
You’re the girl who likes to laugh and make your BBFs laugh with an endless supply of jokes. Look for dress styles that let you have fun with fabrics, maybe mixing and matching patterns, colors and textures. A flirty short Prom dress is on your shot list.

Rainbow bright colors capture your attention - and everyone else's! Who doesn’t know that when you punch up the color, you pump up the fun factor.

As Class Clown you may note take yourself too seriously. But you do take shopping for a plus size Prom dress very seriously. If anyone stresses out on the Big Night, your laughter will be the best chill pill.

Hipster 
You’re the Prom girl that no one is surprised to see you at show up on the big night dressed in a denim jacket over a red strapless ball gown. After all, you are an independent thinker when it comes to making a fashion statement. And you would never think twice about what everyone else is wearing to Prom

At the top of your wish list is a dress with vintage vibe for Prom 2021. The eccentric, effortless Bo-ho looks works for you and speaks to your free fashion spirit.

Preppy 
If you’re in the Preppy Crowd, it’s predictable that you’ll shop for dresses designed in clean, classic lines but with an oh-so modern look. You may not be ahead of the fashion curve. But you are never behind. You favor fabrics that flow over your curves and avoid fabrics that cling or are too tight. You don’t shy away but prints but prefer the patterns have a note of sophistication or playfulness. A minimalist design lets you accessorize with pearls, what every classy Prom Girl wears to pull off looking pretty. The bling, bling is not your thing!

Glam Rocker 
You’re the girl who gets down to details that make a difference in a Prom 2021 dress. Your fashion taste moves to the beat of fancy floral prints on deep dark backgrounds. An animal print attracts your attention especially as a lining in a hot high-low design. You’re definitely not afraid of getting spotted on or off the dance floor. The roar of the animal kingdom calls you!

You love any gown that shimmer, shines or sparkles. A black plus size Prom dress tops your wish list and you’ll pair it with a lace low cut boot with high heels.

Girlie Girl
Once upon a time you dreamed of being a Prom Princess. So it’s natural that you are drawn to a fairy-tale ball gown that captures your Prince Charming. You never get bored of pastels especially in sugary candy land colors but with a modern edge. Bright Prom dresses send you reaching for sun glasses. You love lace dresses because they are coquettish but avoid the naughtiness that can come with that romantic fabric. You don’t leave home for Prom 2021 without your tiara.

Hello Hollywood
You’re a fan who follows what your favorite star wear on the red-carpet. You love all metallic fabrics: gold, silver, bronze and even rose gold. They all work for your over the top glam look. You’re drawn to sexy styles like a fit and flare Mermaid design that hugs your great curves. Nothing but an eye-popping Prom 2021 dress works for you as you practice posing for the cameras in your gorgeous gown.

Want to make a stand-out fashion statement at prom? Shop our 2021 Tease Prom Collection of gowns that are available only at fine dress shops.

Buyer Beware of Fake Dresses

Remember, authentic Tease Prom designs can only be purchased from a retailer authorized to carry Tease Prom dresses. If it's too good of a deal, then it's not real! Unsure? Ask us!

Head to Toe Glam

Don't forget you'll want to look gorgeous from head to toe on Prom night. Once you have your gown, start shoe shopping.

Practice walking in your new shoes before the big night so your new soles are comfy for a big night of dancing.
