After Eden Double Boost Lace bra in white and black in an A and AA.
This will increase your bust by 2 cup sizes! They call it a gel bra but it very much feels like padding. The cups are smooth but the wings are lace. The straps that are attached to the wings at the back are detachable so you can do a cross over in case you’d like to hide the straps when you’re wearing a sleeveless top.
