Flow Y Bra IV 4 5 726 728
A Trusty Fave I like the way that the straps at the back don't cross the shoulder blades. A minimal design that is functional and comfortable. Also am waiting for some brighter colours with a darker shelf liner as I like to leave the cups at the store. The current lighter shades are a bit see through. I'm between a 6 and an 8 (34B) and have found the 8's more comfortable. March 28, 2015
BE CAREFUL when Selecting a Size! I love this bra, but I take some issues with it---mostly because of the sizing. I have a Flow Y that I purchased a while ago, but I never wear it. I purchased it in a size 8, which fit fine in the store (the sales rep even told me that 8 is "definitely my size" and that I look "way too small" for a 10). It fit a little snug in the store, but was not uncomfortable. Unfortunately, it DID NOT fit when I tried to work out in it. I had read some of the reviews mentioning the bra stretches out, so I figured that the slightly-too-tight straps wouldn't be an issue once I started wearing it. I was sooooo wrong. I wore this bra for a hike (not even a high intensity activity) and, by the end of the hike, the straps had rubbed my shoulders raw. I'm pretty built and have lats and traps, but I was not expecting this to happen. It was so bad that my husband even commented on how red and uncomfortable the chafing looked, and asked if I wanted to go home early (I didn't). This was the worst that any bra has ever chafed/rubbed/strangled me. By the end of the day, I had two huge red marks (one on each trap), and I was dying to take the bra off. Since that day, it has sat at the bottom of my sports bra drawer, collecting dust. I now own another flow y bra in a size 10 (I made VERY SURE to wear it for a while in the store before purchasing), and it has become apparent to me that this is a sizing issue. I love my size 10 bra. I got it in the inkwell prism color way, and it's gorgeous and fits me perfectly. It's not quite as compressive as I would like a bra to be for a WOD or any type of HIIT (I don't think it could handle jump squats, rope/med ball slams, or KB swings very well), so I wear it for hiking, walking, errands, etc. I like it for those activities, and consider the money that I paid for the (size 10) bra to be money well spent. No issue there. I do, however, take issue with the insane Lulu return policy. I'm now stuck with a $42 bra that I have no intention of ever wearing again. Needless to say, I am super disappointed. In my opinion, if we are paying this much for workout gear, we should have the option of trying it out and then returning it. All the competing big athletic-wear brands allow for customers to test their gear and THEN decide if it's worth the investment. I honestly feel now that, whenever I buy a Lulu item, I am taking a (pricey) gamble. This is an issue even with Lulu items that I already own and am familiar with, due to the lack of consistent sizing and the quality control issues (I'm thinking of the speed shorts, which seem to be sized differently every time I buy a new pair). Please consider allowing customers to TEST the gear first! Back to the Flow Y: to be clear, I like the bra, but because of the situation and the customer service, I'm giving it 3 stars. For size referencing: I wear a 36B/34C in VS, an 8 in the energy bra, and a 10 in the free to be wild. A size 8 in the Flow Y fits, but the shoulder straps are very uncomfortable. 10 fits, but is not compressive. March 27, 2015
great for everyday and the gym Excellent everyday bra from work to gym. I wear this bra every time at the gym for lifting and it provides support and comfort. It's great for benching because my shoulder blades are free. One thing I don't like is the straps will keep flipping when you move. Would be great if the straps stayed in place. I went a size down for this bra. It's my favourite lululemon bra and I highly recommend! March 21, 2015
Simple and my favorite Hands down my favorite sports bra. I basically live in them. I wear to yoga, gym, running, lounging - anywhere! I have a couple and wear them often and wash them with care and they still look good as new. You can move easily in it and it keeps you dry. Nice and simple design, will go with anything!

LOVE THIS I am an avid crossfitter and coach and this is my all time favorite bra. Usually wear a 6 or 8 in bras and this one is true to size. I like the cut MUCH better than the energy bra, especially for a more athletic build. I am 5ft 7 138lbs and I have both 6's and 8's. the 6's are just a little tighter but the 8's are more comfortable. March 10, 2015
let down 5'5" 140 muscular build, bought an 8 I bought this bra on recommendation from a friend, sadly, the seam on the sides just below the arm are terribly placed. Additionally, the fit of the bra is very awkward and creates unsightly squeezing near the chest. I wore this bra twice and tried to love it but ended up burying in the back of my bra drawer. Not impressed with this bra. March 3, 2015
Disappointed Over the past year I have purchased this sports bra twice. I find this sports bra to be extremely disappointing. I am a dance instructor and use a sports bra on a daily basis I wanted something that I would feel supported in but I didn't need extreme support. After purchasing this sports bra the first time it completely stretched out. It stretched so much that there was a space between my breastbone and the bottom elastic. Needless to say I loved this sports bra at the beginning so I figured I would repurchase it hoping that the second one might have a stronger elastic. To my disappointment once again I am left with a sports bra that is over stretched and double the size. Do not waste your money on this sports bra! I am a lover of lululemon and always have been, however, I cannot believe how disappointed I am with this product. Sincerely disappointed customer :( February 24, 2015
Awesome while it lasted I am a rock climber and yogi and absolutely loved this bra while it lasted. It felt and looked great under a shirt and it was also flattering and had enough coverage to wear on its own while climbing outside on hot days. Unfortunately it lost its shape really early on. I took it into two Lululemon stores and was told at both that it lost its shape due to wear (isn't that what you're supposed to do with it?). I would have expected more given the reputation that Lululemon has for durability. Despite the short lifetime, it was such a functional bra, I would still buy another one. I really hope that Lululemon will make another bright colored (orange would be awesome!) one soon so I can replace it! February 23, 2015
Disapointed I purchased this bra when I first started doing more yoga. It was comfortable and I loved it so much that I even purchased a second one. I'm disappointed to say that they didn't hold its shape. When I'm moving in class, I find myself worrying about spilling out of the bra. I have not changed in size. For the price of the bra, I figured it would last and I do believe reading somewhere that lululemon gear is supposed to last a few years. In my case, it didn't even last the year. February 17, 2015
Not so great I wanted a sports bra that I could easily slip the shoulder down so I could nurse while wearing it. This bra fits that criteria, but the coverage is all wrong. I don't have very big breasts at all (34A/B), so I should fit into the size 6 according to the size chart. It fits around my body just fine, but even though my boobs are small I feel like I'm *spilling* out of the cups. It's too low, especially the part between your boobs and underarms. The cups are hideously shaped. I fill them out just fine, but they make me look like I have puffy nipples because the middle of the cup is so strange. So that's fine, you can just remove the cups. But with or without them, the bra completely flattens your boobs and seems to push them downward while at the same time forcing them to spill out the top and sides. It's a sports bra, so I wouldn't care about the boob-flattening if it had more coverage (the lack of coverage by the underarms is what bothers me the most, I don't mind a little cleavage at the top). But it's just a super awkward fit, in my opinion. I may try a size 8 to see if my (small) boobs are covered better, but I'm concerned that it will be too big around. I know I can return the bras when they don't fit, but I don't have a functioning printer at the moment, so it's really a hassle. February 10, 2015
