if you have time, i recommend going to a seamstress and getting cups sewn into the dress. i have zero cleavage and have it done to all my dresses, mostly so i dont have to wear a bra, but it adds a little cleavage as well.
the stick on things
oldcheermom recommended will give you some oomph, but i don't recommend them for prom. i used them for some formal and they were great for pictures and beforehand. as soon as i started dancing and even slightly perspiring, they started sliding down my entire body. so unless you want boobs on your stomach, don't do it :p
Thank you!!! I think I will see if I can get that done:) thanks!
beautiful dress though! and IMO it looks good without cleavage! but whatever makes you feel most comfortable! have fun and be safe :D
