I have no problems with the cup shape.  I like the wide part of the straps.  I was surprised that a 38F would have only three hooks in the back, but it seems like it will be okay--mind you, I haven't worn it yet.  What I DON'T like is something I find on most bras these days--elastic straps!  Non-underwired breasts need MORE support, LESS bounce--how can that happen with an elastic strap?  I can't believe there are any women designing bras.  I'll update this after I've worn it a few times, but I know already that I WON'T be wearing this bra in zumba class!
