This is the Allison Push-Up Bra. True to size, it gives me more cleavage than I've ever experienced, but unfortunately the band is not quite tight/supportive enough to keep it from sliding back out of the cup. The underwires have a pronounced \_/ shape that is too narrow for my wide breasts. Straps are removable/convertible.
This is the Allison T-Shirt Bra. It runs true to size and gives nice lift, but the wires are not wide enough for me. Too bad, because it's a well-thought-out t-shirt bra. The band has a seamless cover and avoids creating bulges. The cups are attached to the wire at the bottom of the channeling in order to hide the wire under clothes, and the curve at the top of the cup also disappears under clothes.
