Loved but doesn't hold up Loved this bra, and literally wore it everywhere. Only a few months after I got it, the straps have stretched out so much that it is now basically unwearable. So mad because it was awesome for its short time, but I don't feel the need to buy another and gamble with it happening again. September 11, 2014
Good Support I recently purchased this bra. I am a 34C and the 8 fit best. I wear an 8 in all the sports bras I have from Lulu. It gives great support during my CrossFit workouts. I own both the free to be and energy bra and I think this is my new favorite. It is definitely more supportive than the free to be bra but not as restrictive as the energy bra. I would highly recommend it. September 11, 2014
no complaints Can't find anything wrong with this bra. The black,white, and tan striped combo is really different and attractive. Usually I think all the crazy striped prints lulu comes out with are ugly and garish, but this one is nice. I'm petite, a size 34C bra, and about 120 lbs. I usually wear a 6 in lulu bra tops, and got a 6 in this one too. It's fine. The straps are pretty tight, so I can see how it may pull or be uncomfortable on someone bigger or taller, but for my body type it works. I feel pretty supported, though an extra 1/2 inch of fabric covering my chest would make me a little happier. Bought this alongside the new Refresh Racer tank and am happy with both. Lots of lulu items are overpriced, but these 2 are worth the $42.00. August 28, 2014
Not just for Yoga! Pleasantly surprised how well this worked out during Zumba class tonight!!! Very comfortable!! LOVE the material!! When I first tried this on today, was a bit concerned that it was going to be too big, but it turned out much better than I thought! I'd ordered an 8 from WMTM, but usually wear a 6 - which was sold out. Way more supportive than I'd figured also, so I wasn't self conscious in it at all. It's not quite as supportive as the Energy Bra, but so much more supportive than I'd imagined it might be. Between this and the Energy Bra I will be purchasing more colours for sure! The Inner Heart Bra is also a fav, but it's not available anymore. Recommend highly! August 27, 2014
WAS a great sports bra I used to love this lulu sports bra, it was a good fit and enjoyable to run/exercise in. I have only had it for a bit more than a year, and sadly it has stretched out... It is loose and not as comfortable to use for working out. All my other lulu products I love! Not sure why it has stretched out so much.. August 26, 2014
light with some support I have an active job as an Athletic Therapist I find underwires to be a little restrictive/uncomfortable to work in especially if I'm going through exercises with patients. Regular sports bras - that I love to work out in just don't do much for your shape ;) So this offers a little bit more shape with the extra padding for everyday wear but just as comfortable as my nike sports bras I love.

One lulu is not like the others This is my first review, and have been a lulu lover for many years. It saddens me to say that the quality in lulu has noticeably gone down hill. I have over 10 lulu bras, three of them are the Y bra! I absolutely LOVE the fit and comfort of these bras and would recommend them IF the quality of the old Y bra that I have come to love comes back!! My most recent Y bra has gone kinky and twists onto itself at the elastic band! None of my older Y bras after many washes are nowheres near what this bra looks like! Bring back the old Lulu quality that we all know and love!! August 23, 2014
Love this bra, exceeded my expectations. I love this Flow Y bra IV. Over the past two months I purchased the Steep stripe black to wear with my first Cool racerback and have to say I am impressed. I was so happy I went back and bought another one right away, in pop stripe heathered light. I am 5'4 and muscular fit, being 36DD I have a very hard time finding bras that hold up or that are comfortable to work out in. I bought the size 10 and it is perfect for sweaty workouts. I really enjoy the mesh back where I tend to sweat often. I use these bras to do crossfit in and I was impressed to be able to do wods and not have to worry about flopping around. I would like to see more solid color choices, also more mesh in the front would be cool. August 15, 2014
Beautiful, but it's coming apart I love the fit of this bra and how comfortable it is! It has good support and coverage and it seems to be of good quality. However, I have worn it only twice since I got it and the seems on one side are coming apart :( I really like the fit and look of it, but I would have loved for it to stay in good shape for longer.

Never buying another type of sports bra My sister has worn lulu sports bras for years and I never understood how she paid so much for a sports bra. I love lulu products but I've always purchased less expensive bras from other stores. However, I tried on a bra after talking to an incredibly helpful woman in a lulu store and LOVED it. I decided to buy just 1 and have bought 4 more since then. I will never buy another type of sports bra again. I'm a 34 B so I don't need a TON of support, but still some. These bras are perfect for me. They give me a little boost that most sports bras lack and are supportive enough and comfortable enough for some many different activities- running, yoga, biking, and just running errands or hanging out. Love this bra! August 1, 2014
