Ordered a small, wear 3/4. This dress is not for anyone over a size 3/4 in a small. If you have a big butt or boobs bigger than a 34a you will need to up size to a medium anything over a size 3/4 do yourself a favor and get a medium this is coming from a true pattern maker/seamstress of fashion. The waistline has absolutely no stretch. Your waistline will need to be the size of a straw (lol) to button this up. I could barely button this up and I have a small waistline. The sleeve arms are tight barley any room. You will need to air the fabric out by hanging it outside a few days to get the smell out. I gave it a 4 due to those reasons I have listed. The dress is beautiful just wish it was executed better. All and all its a great throw on dress to run errands in and look good.
