I LOVE this padded sport bra! It fits like a dream, and it's hands down the best sports bra I've EVER owned. The band isn't overly tight and it provides the perfect amount of support for everyday loungewear or for a sweaty day in the gym. The padding/cups doesn't shift or feel weird- it's just right, and it stays put right against my boobs. The blue and white tie-dye design is beautiful, the straps fit perfectly, the back straps are cool, and the bra material is super sturdy and solid. It wicks away sweat and never gets uncomfortable. The center area is ventilated on the inside with breathable mesh, which is a really nice detail.
For your reference: I'm a petite woman. I'm 5'1", about 110 lbs., and a 34B. I purchased the Medium and I'm very glad I did. I believe a small would be a little too tight, and this fit feels magical. This bra is specifically designed for A and B cups. I'm so happy I got this and I'd encourage you to do the same. The quality of this sports bra is excellent without a ridiculous pricetag. I feel like I can sleep in this!
