For a small person, I'm large chested (some of it is fat on the sides), requiring a 32DD, and a 34D doesn't quite hold the girls without making them spill over a bit on top. I NEED a bra that drastically reduces movement from intense activities like running and kickboxing. I have the Moving Comfort Fiona, and it's great, except for the uni-boob. The Maia is the same level of support without the uni-boob. Hurray! It is not for casual wearing, though. This bra in your proper size will hold you in and feel a bit too snug after several hours. On the other hand if you're running a marathon, you'll need the support and it won't be uncomfortable.
