I LOVE THIS DRESS!!! I cannot express how much I love this dress, it is perfect! The colors are vibrant, the material is good quality and it's sooooo smooth and beautiful, I felt like a queen in it!
I am 5'3" and 225 lbs and I got an XXL and it fits perfectly. The material is slightly this and you can probably get away with not wearing a slip under, but I definitely felt more comfortable with a slip under. It is a tad bit long in the front while I am bear foot, slightly drags on the floor (maybe a 1/4 inch), but the belt helps with that and any shoes that aren't flats will pick it up off the floor.
My husband loves the dress on me, says it is his new favorite of mine. And I got several compliments on it from total strangers too!!
I will probably buy more in different colors!
