If bras were classified as gentle, moderate, or serious support, this bra would be moderate.  That said, I wear a D cup and it holds me in without smashing me.  I used the size guidelines and got the right fit.  The bottom band does roll up, but it's far more comfortable than an underwire digging into your chest and underarms.  The band being really wide helps a lot with the comfort and prevents the extra fat rolls you get in your back from a skinny bra band.  These are the only bras I wear now.
