For reference: bust 35" (36D), waist 30", and hips 39" and I bought a size 8. Fits perfect--not too tight or too loose. Versatile, fits with any bra, and I like the knot look. It's perfect for hot and humid days when you don't want to wear anything, but you kinda have to wear something... Planning on getting this tank in white as well! Hope they come in other colors too!
