This strapless bra was head and hands above the more expensive one I bought and returned.  I did find it a bit tighter than expected, though the cup size was accurate.  I returned it and bought a band size larger (36C to 38C).  It wore well in a very hot vacation climate and didn't slip at all.  I definitely would recommend this bra to anyone who wants to look great in dresses that require a strapless bra!
