I wear a 34C in almost every bra and generally the only sizing issue I encounter is when cups are too widely spaced. I could barely get the 34C of this one to close, even on the widest hook and the "muffin top" created both above and below the band was terrible.
I *think* that it might be an amazing bra if sized correctly but with such a serious difference in band sizing (at least 1 if not 2 sizes off) it's impossible to tell.
I'll be exchanging this one for the 36C and keeping my fingers crossed but its possible that all but the tiniest among us will be sized out.
:(

The fit and feel of this bra is very different from anything else I own. There are no wires but its supportive, uplifting and flattering... My shape is very wide and shallow and even I rock cleavage in this plunge bra! The band is a strange texture (spongy or rubbery) and VERY taught when you first put it on but it conforms to a comfortable fit after about a half hour of wear and stays put all day. (I ordered my regular size, 32D). True to Stella the moulding is barely there and cups are invisible beneath clothing. The far sides of your breasts aren't incorporated into the cups and that's a little different. Overall its sexy, comfy and very utilitarian if you give it a chance - I love mine.
