I think so! I'm a size 5 34 c and the small is pretty tight fitting so honestly the med is prolly perfect! This dress is Strechy enough that you would have to be under 100 lbs for it to not hug you body
I think your right but I just but a pic of the back as my profile pic. There is no studs or designs on the back, just plain pink :)..such a great dress, I'm excited for whomever wins it!
