While I love the short satin dress from Amazon that I've featured a couple times on this website because it's so popular with brides, I realize that a lot of brides or bridesmaids, (or even girls looking for prom dresses under $50) would prefer a longer, floor length gown.
This was newer to Amazon than the shorter version but it's similar and really, quite beautiful! These dresses are available in a wide range of sizes but remember to be honest. They are sewn to size and this dress runs tight.
While I should probably show it in one of the many colors it comes in (black, blue, red, purple, etc. etc.) I can't help it... I love it in white best!!
