All reviews are correct in saying that this dress runs VERY small. I would highly recommend sizing up 1-2 sizes, depending on the fit you want. I bought this dress for my birthday and it did not disappoint! I felt so beautiful and got so many compliments on the dress. I didn't wear shapewear but still felt really snatched. A couple downsides: Absolutely ZERO stretch, walking is very difficult as it's tight around your ankles so you have to take very small steps, you can't lift the dress up to pee so you have to take it off entirely to pee then zip yourself back up, my dress did rip in the back on the first wear, likely from zipping and unzipping so many times throughout the night, but I still think it was worth it. Such a stunning dress!

Overall size M, only problem is there's not enough space to to open legs while walking..
