Flow Y Bra IV 4 5 708 710
comfortable sports bra I love this bra! It's so comfortable and very cute to wear. It's my go-to bra and the first one I grab whenever it's clean. I bought a size 6 and I wear a 32C everyday bra. I also own the energy bra (size 6) and the flow bra band is not as tight. I probably could have gotten away with a size 4 but I was nervous since the energy bra is so tight on me. Either way, I love it and would buy again! December 15, 2014
come on, lulu! I think this bra is gorgeous and it gives me wonderful support, however, what's up with the huge seams underneath the arms? You can see the seam I'm talking about (bottom photo above)... it didn't bug me at first, but after wearing the bra for more than an hour (nevermind long runs with it) it digs right into my side. Lulu designers, please consider eliminating or moving this seam to the top of the strap... or eliminating? December 4, 2014
TOO SMALL I wanted SO BADLY to love this bra. I bought this and Ebb to Street and both were too small. I am a slim, 140lbs 5'10" - and a 34 B. I wear an 8/10 in other Lulu tops. The size 10 bras cut into me and I could not move freely in either one without pinching and TOTALLY flattening my girls out (uncomfortably so). Sadly both bras had to go back. I probably won't try another one. I can't believe that at my body size, I should be ordering a 12. That's crazy. Lulu, please PLEASE reconsider your sizing. It is very disappointing. December 1, 2014
worth giving up traditional bras for These bras last forever! I still have two from two years ago and they are still going strong. They are super comfortable! I find it hard to find bras that are wide enough for my back, and not too big in the front! I'm a 36A and size 6 fits me perfectly. November 30, 2014
great all purpose bra This is a great bra for running and yoga (my two favorite activities). I'm a 36B and wear a size 6 or 8 in lulu bras, this provides great support and coverage without being constricting. I also really like the newer detail of luon covered elastic- much improvement over my older versions! November 9, 2014
Poor Quality I purchased this bra about 2 months ago, have worn it a handful of times, and the stitching is already unraveling. This is very disappointing both because I did like the bra, and because despite the steep price I only got a few wears out of it! Based on the reviews of many Lulu products, quality seems to be a growing issue. I will definitely think twice about future purchases. This is way too expensive to fall apart after just a few times wearing it. November 7, 2014
Loved at first but now disappointed This use to be my favorite bra. It seemed to last longer when I first started wearing these bras. Now the straps stretch out in no time allowing no support and the bra begins to sag. Really disappointed that this style is no longer my favorite bra. October 20, 2014
Great Favourite sports bra for my workouts and just for everyday wear. I hate regular bras. I'm a 32DD and a size 6 fits perfect. October 18, 2014
Undergarment Feedback I am a big fan of most of the bras- particularly the energy, flow y, and the free to be wild (my back is broad so the wild fits better that the regular free to be). I dance professionally and we have nude colored undergarments that we wear under most of our costumes. The bras have clear straps that can be detached so they can cross or halter or go straight back, and there is a clear strap across the back too for backless options. While those features are great, all of the nude bras and shorts that are created for dancers are extremely unsupportive and have poor quality, thin material. None compare to the quality and support of the lulu products. If lulu could make some sort of professional undergarment series of bras and shorts for purposes such as this, I know a TON of dancers who will be eternally grateful. October 17, 2014
LOVE This is my every day bra. I would not wear it for workouts but for everyday wear it is beyond fantastic. Unparalleled comfort. I only wish I could have 10 of them! October 17, 2014
