Hey there, good looking! You love your womanly figure, and here at Unique Prom, we do too.

Forget crowded mall dressing rooms and expensive boutique stores — when you want to find a fabulous plus size ball gown that really fits, Unique Prom is the only shop you need!
Short formal dresses are fun and youthful, and they show off your great legs while keeping things modest on the top. If you’re looking for a plus size formal dress in knee-length or above-the-knee length, our selection by Sydney’s Closet, Flirt by Maggie Sottero and other top brands is one of the very best. These sassy cocktail dresses feature deep jewel toned satin colors, elaborate sequined designs and even silly polka dots to suit every girl’s unique tastes just as much as her body type.
Floor-length plus size gowns look gorgeous for dressier occasions, from proms to pageants. Whatever formal event you have coming up, these beautifully crafted dresses by brands like Night Moves by Allure and Faviana will make you feel your most confident all night long. Choose from dark, romantic colors like purple and black, bright, eye-catching pinks and greens or neutral silvers and golds to create the formal look of your dreams.
All Unique Prom plus size special occasion dresses are created by the top plus size brands for young women today, including Faviana, TOO by Blush, Sydney’s Closet and more.
