This bra does what it says.  It covers the breasts and can provide slight lift if positioned slightly higher than suggested, but will NOT  add cup size.  I don't think it will support a fuller C leaning toward D size of natural breast, but may work well for augmented breasts.  If your breasts have lost elasticity this is NOT  the product for you.  This is meant for already firm-ish breasts as a " material" to stand between you and your clothing nothing more.  Overall good product seller was fantastic in replacing a damaged product due to crushed packaging(or nosey ups delivery person).  I give the seller Fashion888 5 stars as a seller
