Elomi Response: Did the Abi bra tack in the center gore? The bra should lay flat in the center of the breasts, if not the cup is too small. If the bra was poking you under the arm it could be that the wire goes up too high under your arm causing it to hurt, or it could be that the cup is too small and therefore cutting your breast tissue on the side. Sorry it did not work for you, this bra usually fits really well. Melissa from Maryland
