I really love this Avia sports bra! It is my absolute favorite sports bra- ever! It is extremely comfortable. For sizing purposes: I am 5'4”, 135 pounds, and normally wear a 34C bra. I don't like very tight sports bras- they make me really claustrophobic. I got a size large and it fits like it was made for me! Don't hesitate to order a size up if you're like me and want a really comfy (but still supportive) fit. Order your normal size if you need extra compression, tightness, and support. There are no wires, no parts that are scratchy or that squeeze or pinch, no straps that dig in, and no uncomfortable spots whatsoever. The cups are lightly molded to provide good coverage and an even, smooth look under clothes. The adjustable straps are nice and thick and cross in the back providing plenty of support and ease of movement. The elastic underneath the bra is nice and thick, but most importantly, it's really supportive and very soft and comfortable. It doesn't dig in, and it stays put and doesn't ride up. You get a super sleek and smooth look, which makes this not only a great sports bra, but an excellent t-shirt bra too! You won't have any weird seams, lines, or lumps or bumps. It completely smooths you and looks great under even the clingiest of T-shirts or tops. I like that the zipper closure is in the front, which makes it easy to put on. There's also a little hook closure in the front that you use before you zip to make zipping it up super easy. This Avia sports bra is such high quality and the attention to detail and excellent quality fabrics are impressive! When compared to brand name sports bras, believe it or not, this one is the absolute best I have ever owned! The zipper also has a little fabric panel under it, so the zipper never touches or digs into your skin. This Avia bra also has mesh fabric panels on the straps, on the sides, and the back, which makes it breathable and encourages air flow and prevents sweatiness during exercise or regular wear. You'll get great comfy support for all kinds of exercise, sports, aerobics, running, etc. I absolutely love this Avia sports bra and don't have anything negative to say about it! I'd highly recommend it for anyone looking for a high quality, comfortable, supportive sports bra!
