I might try one size larger. Based on my band and cup size I fit into three different sizings. I chose medium. Luxe is the next size up. I'm buying via amazon so they're easy to return. It would be nice not to reach behind me to fasten the bra.I would exchange it becuase it should not create the side boob if fitted properly. I do love the wash bag, it keeps my she fits nice while washing & drying.
