Great Sports Bra!!! This sports bra is awesome! I just received it in the mail, and am already in love with it. It's great for everyday wear, as well as sports. It holds the boobs down when running, but gives them just enough lift for anything else. The Y-shaped straps allow for a full rnage of movement when running, and don't cause my should pain like my lulu FTB bras do. The mesh is a great feature, as it keeps your back cool during those sweaty workouts. For reference, I am 5'3, 117 pounds, 32A and the size 4 fits me perfectly! April 23, 2015
Very comfy, but runs small I was looking for bras for lounging and running errands in, and this is a perfect bra for that purpose! I initially tried my usual size 6, and it was a bit too tight. Then I ordered 8, and it feels perfect. I am a A cup and don't need much support at all, and I feel there is enough coverage. It feels sort of crazy that I wear size 8 bra, although my street size is 2 and my bra size is 32-34A! However, for high intensitiy workout, I prefer more tight fit, and more coverage, so I use size 6 Energy Bra. April 22, 2015
Favorite Bra! I always look forward to new colors and have a Flow Y Bra collection! I am small chested & think this is the most comfortable bra. I lift weights and love the amount of stretch both around the chest & also over the shoulder. Keep them coming! :) April 21, 2015
Cute, but serves little purpose. Cute bra, has 0 support. The straps are a little too long and unadjustable. Ok to wear under something that has good coverage. Great for Yin, best suited for a small A or B cup. April 20, 2015
not enough fabric on this one I was so excited when my lululemon bra showed up. I don't have a store anywhere close to where I live and it is very hard to order bras online. This bra wound have been just so perfect except there is not enough fabric on the front side. The fabric on the front side barely even covers the breast and nearly exposes the areolla. If this bra had even 1/2 inch or 3/4 inch more fabric superiorially then it would be ideal. I am so bummed out. April 17, 2015
go-to sports bra I've lost count of how many Flow Y IIs I've bought. Super comfortable, don't dig in anywhere, and good enough support (as a smaller chested girl at least!) for running as well as gym/pilates etc. All time favourite sports bra. I do take a size down from my usual lulu top size though. April 11, 2015
A Different Bra? I love the Flow Y bra for doing Pilates, as it provides ample coverage for the girls (for reference I am a 34D but have a wide upper rib cage) but is not constricting as a high impact bra. I used to have a few and found that my bra size had increased, so off I went to go bra shopping. What I've realized is that every woman is built differently, and though you may share the same cup size and band width, there are different nuances to your body that will cause one person to hate a bra and another person to love it. I don't know what they did to the new Flow Y's, but I love them more than my old ones. My old ones were cotton, and that was fine, but I bought two that were stretchy synthetic, and I found that hugged my chest more comfortably and were a bit cooler. I found there was ample coverage up top and felt comfortable and light support. I can imagine if you are broad shouldered or have a wide ribcage that this would be a tad big (or you would need to size down). I really love the redesign of the bra, as the other light support bras tend to need at least an inch more of fabric, as I'm not a fan of showing my cleavage to the world when practicing Pilates.

Stitching coming apart I have always loved the look and fit of the flow y bra on me and have one in the pizzazz orange colour, one in the love red, and one in a deep blue. I ordered a lighter blue one and in less than 3 wears, the lower stitching all across the band of the bra was coming out.... I have never had this problem with any of the other bras and it's a shame because the one I ordered is in my favourite colour. :( April 5, 2015
Bit tight I love this bra, especially the mesh in the back where I sweat the most. The only thing is that the band on the bottom is a bit tight and the sides of my chest aches after wearing it fit long periods of time. April 4, 2015
I enjoy it better than the energy bra. I own three energy bras that I love. I was about to order a fourth but decided to try something new. I ordered the Flow Y in the same size as the energy bra (size 6). It fits amazing and is more comfortable than the energy bra -- as it is not as tight around my armpits. For reference: I wear a 32DD in Victoria Secret and a 6 fits well. April 3, 2015
