FAQs

Q1. What undergarments work best with backless prom dresses?

Ans: We suggest that you wear an adhesive bra, silicone petals or a built-in cup gown to keep your backless prom gown clean and smooth. Many of our gowns also feature a structured bodice or adjustable lace-up ties for supportive wear, and most will eliminate the need for a traditional bra. 

Q2. Are midi formal dresses appropriate for a prom?

Ans: Yes, midi formal dresses with an open back design are much more popular than ever, and a fantastic alternative for a traditional full-length gown. Wear one take to homecoming or a spring prom and be more mobile on the dance floor, but still look elegant in a fashionable gown. 

Q3. Do you offer backless dresses in plus sizes?

Ans: Yes, we have great plus-size formal gowns in this category, many up to size 24. These are designed with side-boning and strategic strap placement for a secure and most comfortable fit for every body type.
