Couldn’t fit it I needed a X-Large

Thought the dress looked nice so I bought my normal size L and I am 5’6 210 pounds. It fit well, but the side slit is so high that it exposed my butt. Now I am curvy and have a slightly big butt, but the cut is way too high. Also, the material is heavy especially due to the attached jewelry. It’s also not white but more of a off white color. Returning.
