I have a 42 bust and like another reviewer said, anything smaller than a 2x would be too small around the chest. Take that into consideration. Besides that, the dress is great. Soft and flowy material. Has some weight but not too heavy. Stretchy too. Just a heads up, the color on the flower patterned black dress appears more golden in the picture than in person. It's actually more of a peach/orange shade.
Will be ordering more in the future.

I am 5 ft 6 dress is about 2-3 inches above my ankles, besides that it's nice. Just wish it was longer! Using it for maternity photos.

So this dress is designed to be loose so, I bought a medium at first (I’m 5’7” and 140 lbs. I had to order a small and the small fit perfect!
