This is my 2nd Freya Deco Vibe.  I tried the original Deco years ago and it didn't work for my shape, but the Deco Vibe does, as the edging around the top of the cup helps mitigate the openness of the cups. My other Deco Vibe is a 30E (UK) and while it fits, 30 bands just stretch out too quickly for me, so I sister-sized and got this one in a 28F (UK).  My only complaint is that the center gore digs in a bit on my sternum, but that is common for me, especially with plunge styles (usually I can't wear them at all!).
