1106 Simple Packaging The inside of the cups is made of a 100% cotton knit material, providing a smooth and gentle feel against the skin. The lift panel on the back of the cups gathers the bust towards the center, beautifully creating cleavage. Despite being wire-free, it firmly holds up the bust. The "side-flesh push panel" attached to the underarm area prevents side flesh from spilling out while also acting as a sweat-absorbing pad.
