I got a medium, but should have gotten a small. There were no more smalls for the weekend I needed it. I wore it to my prom. The length was fine with high heels, but I had to pull in the straps and the front so I wasn't flashing the world. If I had gotten a small I doubt it would have been as bad. The dress is made for people who are more flat chested. I got a sticky/backless/strapless bra from Target. You couldn't see it unless the dress fell down and the dress is very heavy. I got loads of compliments on it. It is a very pretty dress. I think the model makes the back look a little lower than it is. I wore a bun and loads of pearls and it made for a very classy look.
