I’m 5’6 143 lbs & the medium fit beautifully! It may feel tight while putting it in but as long as you have the correct size and put it on gently, it’ll fit like a glove. cute for loungewear too

I bought this item in both colors. The size is extremely undersized. I usually wear a 2X in dresses from this store. I cannot start to put this on. I estimate the so called 2X is about a size large. I do not know if they will accept a return as it is called a slip dress. Be careful. Size up two sizes.
