I got a 3X, it fit exactly like I'd expect a 2X. The pleats didn't sit nicely because of it. Also, it was really difficult to get the wrinkles out of the top with ironing - perhaps it was just the hotel iron but those were some stubborn wrinkles. Spritzing with water and letting it hang (my preferred method) didn't work either.

Other than that, I like the fabric, the style, etc. The weight of it is best for a winter dress.
