I’m usually a size small/medium i am 5’4 and 126lbs. The reviews i seen said to size up so i did just because the top runs small which actually fits pretty good since i sized up but the dress is a little too big sadly but its so cute. if i got a s/m the dress would probably show a little more booty but with the size i got it just flows right under my butt. since i have small cups lol the dress falls off but i’m still gonna wear it lol a little fashion tape and a waist clip to snatch me up will do. i say stick to your original size so you can be snatched since halloween is the only night wear a girl can dress like a total SLT 💖
