Love it! Silky fabric, no binding or chafing, super comfortable, super supportive, rich color. It is a compression style bra, so it gives a little uniboob effect, but that's what I wanted. I got this for high intensity cross training workouts, so it keeps the girls from bouncing much and keeps them more out of the way. It's definitely snug but feels very comfortable to me. It does give quite a bit of cleavage/ swell at the top, too! I'm a size 2 in jeans, 5'5". I don't know my weight or bra size. I was a 34d before a reduction 12 years ago, and I'm probably a 34b-c now? (They've grown back some!) I generally wear a S in tops and camis, but a M in sports bras. I got this in a M and it's perfect for me. Other reviewers have said the band should be smaller, compared to the cups, and that it doesn't stay in place. I can see that this might be an issue if you don't want a compression style bra, or if you have a larger breast to rib cage ratio than i do. I love it and will probably get more. I have a few Under Armour products now and find them to be very comfortable, functional, and high quality.
