It’s hard to find light weight dresses when you are naturally busty. Everything seems to require a strapless bra, a "trick” bra or that you be a smaller chested waif. I’m 34G and can wear my normal bra with this dress; I purchased an XL in the black. At first, it was almost too big, boxy and showing quite a bit of my bra on the side. After machine washing the dress in cold & hang drying, it fits better and reveals less.The material is light, but not thin or sheer. Perfect for hot, humid weather See full review
