I usually wear an underwire for support so was hesitant to try this bra, recommended by a friend. After trying it, I'm  convinced, and will buy more of this bra in other colors. I forget I'm wearing it, its so comfy, and it truly is invisible under T-shirts and clingy knits. Also offers good support and a youthful profile. If there is a down side, the straps aren't adjustable, so I wonder if the bra will "sag" as the straps become stretched out from use. Will update review if that happens, but at this price point (half of what I'd usually pay at Soma or VS) it shouldn't be a big issue.
