My Go To Sports Bra I rececntly cleaned out my closet and threw away all of my sports bras except these ones! I find it to be very confortable and I like that the straps stay hidden under almost any shirt that I wear. I find that it is supportive enough to run in, but I don't have much to support.

Straps are uncomfortable, unflattering I purchased this bra about a year ago, my first flow y. I loved the color and when I tried it on in store the size 8 fit was perfect so I took it home. After working out in it (pilates, so def not high impact) the straps were biting into my back. I had also tried the size 10 and found it too big (i'm not large chested at all). I found this to be probably the most uncomfortable and least flattering bra that lulu makes. I tried it again several months later just to see if maybe I was having an off day and no, it's truly uncomfortable, I really don't like this style at all. Sadly wasted money :( January 11, 2015
Awesome bra! I'm a bra size B34; ordered a size 6 and highly recommend this sports bra for any activity- even running. I ordered this bra online, hesitant about the sizing, but it fits great plus it's adorable. For anyone with small boobs like me, it's worth every penny! January 10, 2015
Straps stretched out I bought two of these about a year ago, and initially they were fine but after infrequent the straps became super stretched out. It is now unwearable because the straps are so long and stretchy that it no longer fits well. January 10, 2015
Swallon spots I love the design and the fit. I would highly recommend it but some reason when i wear this and go for a light walk on a treadmeal my armpit seam line area gets swallon :(. That is the only down side of this bra. Is there any way that i can exchange it to a different bra or the same one? I am attaching my swallon area. Hope that is alright. And hopefully get some feedback and some follow up actions. Please and thank you. I am 5"3 and weight around 53kg. 116ish lbs. HOWEVER THOUGH, this bra fits so well and so fashion-y. Love it!

loveeeee this bra!!! THIS IS A GREAT BRA!!!! I usually am a free to be kind of girl, requiring only light coverage. And I find the energy bra to actually have too much coverage for me. Even though this bra says medium coverage, it is low enough just to be sexy but has slightly better support than the free to be. I'm so excited to have found my new favorite lulu bra!! For the record - i own 2 free to be, 1 50 rep bra, 1 energy bra. Got this in the floral prism design. LOVING IT! January 7, 2015
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
