@nikki18888: Puff works with any tops, low cut or backless, the bio silicon gel has insane hold and works with heavy set like mine. Hypoallergenic, so l can wear all day without irratation. It lasts longer, and economical with the replacement gel, so you don't have to replace it entirely.! swear by these #puffstickybra #stickybra #bra #brainserts #nudebra
