Love it! This bra is super comfortable and provide great support! September 29, 2014
Great bra Love the think straps and simple styling of this bra. September 29, 2014
Simple, yet effective! After having breast surgery, I needed something I could sleep in for awhile. I have many Lulu products and knew the answer to my solution was a few clicks away. Sadly, I ordered a 6, which was too tight. Ugh. I needed an 8 (which I just ordered). The 6 went to my step-daughter as it was final sale. I am 5"6', fit, 135lbs, bra size 34B. After reading the reviews I was sure of the 6, but low and behold, it was extremely binding---even after I removed the cups. The material is soft and the Y in the back is pretty. However, the tag is ridiculous. I cut that out immediately. I think all sports bras should be tagless! Overall, awesome for healing or fitness!! September 28, 2014
have 100 of them in many clolors I like them with and without inserts I got them in these two colors shown - great! September 28, 2014
Obsessed I have really hated Lulu bras over the years. Either crazy light support or the cone bra effect with too many bells and whistles (TaTa Tamer). I'm a small but busty woman, who loves to run long miles and hates underwire, straps, etc. I am 5 ft 4, 115 pounds, a 30DD, and LOVE this bra. I take a 6 (I mean, what lulu, I am a size 2 in real people clothes, but a 6 in yours???), and it's super comfy. Almost like wearing a bralette. Plenty of support, cute and functional, and keeps the girls in place while running (which I never thought possible), but I can wear it for ten hours and not feel any tugging or digging in. Love the breathable back. I would own 20 of these if I could afford it. September 23, 2014
Good at first...stretches a lot over time. Loved this bra at first; bought 2 of them and wore them all the time. Unfortunately, the straps seem to really stretch out over time, and the bra itself becomes less supportive. Perhaps I should have bought a size smaller to compensate for the stretching? I've noticed from the comments that other people have had this same issue with the Flow Y Bra IV. September 22, 2014
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
