black girl prom dresses

Hello FB friends and Family,

I am needing of a Rainbow Color sequin full length evening gown size 20-22 that zips all the way up the back. I have a hard time finding a dress that zips fully up the back due to my shoulders being wide. If anyone can point me toward where I can find one please do. I have tried ebay and amazon and can not find one. Thanks in advance. Deva Anew black girl prom dresses
