Here's a long formal prom dress for the girl who loves her curves. Made in the USA, this long evening gown shows off the curves from the slight sweetheart neckline to the horsehair hemline for a sexy look at prom, island vacations, and other formal events. In misses and plus sizes, this long formal dress has a peek-a-boo triangle-shaped cut out on the pleated bra-style bodice and thin shoulder straps that lead to the low back. The high-waist long skirt opens in a side slit to complete the look of this long formal prom dress that is as sexy as it is beautiful.
