I wear a 44DDD bra and purchased a size 3X. The size chart was very accurate. perfect fit. Super comfy, I forgot I was wearing a bra. I would recommend this for D cup or smaller.
It gives some support and good to wear around the house. I wore it to the grocery store and it was a little too bouncy. I would not jog or jump rope in this bra. However, great for leisurely comfort.
