This fit well (along with the other two I tried on), but I didn't choose it because I felt like it looked just a little too much like a bra rather than a swim top. But it was comfortable!
I'm loving this bikini top! It feels pretty comfortable so far, not too much digging or anything and it isn't falling or slipping down at all either. That said, I haven't been doing too much activity with it on, and I certainly haven't tried swimming with it yet (bring on 1 week and 4 days for Turkey, wohoo!).
I've tried wearing it with the halter on and off and I really love how both look. It's no problem at all without the straps, I tried jumping around and my boobs stayed in very nicely.
I did actually go up 1 cup size more than I usually go for, which is a 27FF. I'm glad I did because I think I would've gotten quadboob from the FF. The G seems to be just perfect for me!
