I'm not giving up on this bra yet, but after wearing it for a day, it definitely has an unusual fit.  The cup size actually seems rather larger (vertically longer) than usual, and the shape is designed in a way to expect you to be always very "perky" for it to fit well (but the cups themselves don't cause this perkiness since the cups are so big (tall?) and gravity starts to set in.  I find that when I'm wearing it comfortably, the cups have a little wrinkled/indented/empty spot where it thinks one's artificially perky nipples should be, but aren't.  It's sort of like the bottom of the cups need an extra inch of padding or something.

It seems comfortable other than that, though, and would have very low visibility under a shirt if it weren't for the issue I mentioned above.
