This is the most comfortable bra ever.  The straps do not slide over my shoulders, there is no side spillage or back fat.  Most important of all, my raging heartburn has disappeared.  I have ordered 3 more so my underwire bras will only be worn occasionally.  The fabric is smooth, does not stretch out, launders well on delicate cycle, cold water wash and air dries quickly.  I wear a 38B and ordered a large.  Great fit.
