While this bra kept my nipples from chafing against shirt fabrics, it did kind of squoosh together and not offer a lot of support.  Maybe because I'm a 42C?  I needed a couple of strapless bras after shoulder surgery and this bra worked for what was needed.  It was supporting enough to wear in public without a lot of jiggling, but the stays at the sides did collapse making the bra sag a bit.  It did what I wanted after my shoulder surgery, but I would not wear this on a regular basis when a strapless was needed.
