I’m a 34DDD woman, which is think is the same as an e cup. I wear the capezio basics line which has a built in bra shelf that is actually supportive enough for my needs, and I don’t need a bra with it. However, the cut would probably hide the bra you want to wear. It’s not the cutest, it’s super basic, but maybe it will work for you!
