This product is perfect for what you buy it for, a racerback tee or whatnot.  It even shows a peekaboo of lace.  but it hurts your breastbone and the small of your neck for some reason.  Maybe that's because I hike it up so high so that I really have super cleavage, I'm not sure.  Other than that, I think this product is fine.  It makes your decolletage look fairly inviting (to people who like that sort of thing).  Don't wear to PTA meetings unless you want the other women to talk about you.
