Flow Y Bra IV 4 5 681 683
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
Very Dissapointed with Quality I got this bra as a christmas gift this year. I have lots of lulu items and I know how to care for them. I always wash this bra on delicate cycle and hang dry. After a few months, the bra started pilling and now it looks like it is 5 years old. There is pilling all over and it apauls me. I should be able to wear a $40 bra for more than a few months without it pilling and falling apart. So frustrated with lulu and their terrible quality. July 21, 2014
My forever sports bra I have this flow Y bra in different colors since I started doing bikram yoga, lululemon you are the best for creating this! Please dont stop makin them. Please make them in solid colors like, blue, red, orange since I dont have those colors yet. They are true to size I am a size 6 in cool racerback as well as in flow Y bra. For reference I am 5 3" 110lbs July 19, 2014
LOVE the flow bra I love lululemon for mostly their shorts and leggings, but once I tried on and used the Flow Y bra, it easily became my new favorite workout accessory. As someone who does both yoga and running, it works for both, and even creates some cleavage, which my A cups always need. Supremely comfortable and flattering, washes well, but I always let it air dry. Already own in three colors. July 17, 2014
It gets better and better I've been Lululemon crazy for the past several months, as I finally got back into my yoga practice after taking a long break due to health problems. I had never purchased anything from Lululemon before because it was a little out of my price range. I also didn't want to buy something I might never actually use more than a couple of times but I finally decided to take the plunge and I purchased this bra as well as several other items to get myself motivated and excited about working out. I am so glad that I did. It took some time to find the right size in this bra. I've worked clothing retail before and I understand that if you're going to wear tight fitting clothing you usually need to upsize a bit and Lululemon is no exception. I am 5'3'' and wear between a 36A to 34B depending on the bra and I'm usually a size small in my tops so around a 2 to a 4. So, I started out by trying on a size 6 in this which fit okay across the chest but was extremely tight in the back. So I went to an 8. I was a little unsure of this size too because it still seemed a bit tight in the back, but after taking out the cups it fit perfectly. This bra does what it is designed to do, and I love the way it looks; I never want to take it off! The only negative things I have to say is that it was a little itchy the first few times I wore it. But I took it into the shower with me one day after class and washed it with some of my tea tree/peppermint shampoo and now it is so soft and even more comfortable to wear than before. Another con I guess I have is the straps twist a bit in the front but it doesn't really affect the comfort or anything so I don't really see it as a deal breaker. Overall, I really like this bra and recommend it but I also recommend trying it on in different sizes first. Finding the right fit is key to making this bra work. I think most of the women who are having problems with this bra (as well as other lulu gear) aren't getting the correct size. Everyone is different so expect that things are going to fit differently too. July 13, 2014
good quality but too costly and no solid colours I love this sports bra and I wear it all the time. Although it was way overpirced for what I got. I still can't believe i spent that much money on it. I got this for cheerleading since my team wears sports bras and spandex, and i always where this bra. We have to wear our team colours (blue, and gold) and i couldn't find just a solid blue which was so annoying. The main reason I was so hassitant on getting this was because of the cost and colour opptions. If the cost was lower and they have a solid blue I would 100% buy 2 more of them! July 10, 2014
Try before you buy! After reading the reviews (and eyeing the price tag with dismay) I finally broke down and bought the Flow Y Bra IV in black and purple/berry. Im a 32A, 5'11'' and 124lbs. A lot of the reviews recommended buying this bra in a size 6 for my cup size. Silly me, I bought the bras instead of going to the store and trying them on. While they were being sent over to me, I decided to kill some time between yoga and class pop into the shop to try them on. Right away I can tell just by looking at this bra that the size 6 was way too wide for me. Sure enough, when I went to try it on, the band under my bust was too wide. It was quite roomy all around and had a little gap in the front. After speaking to an associate (and mentioning the reviews saying to get a 6) she said that she's a 36A and wears a 6 in the Flow Y IV bra (if it matters, we seemed to be around the same height; her having more muscle than me) and that a 4 would be ideal for a 32A. Long story short, the 4 fits me to a T! If you have a lulu near you, I suggest to try before you buy and then order online (hey that rhymes!). Also Im so happy lulu bras come with light optional padding. My headlights always show through my other sports bras! One thing I didn't like about the bra was the tag being visible throughout the mesh at the back. It doesn't show through the model picture but after my exchange I noticed the long lululemon tag showing. Nothing scissors couldn't fix but still. It just didn't look like it belonged, if that makes sense. Overall it is a great bra, the only reason why I wouldn't recommend this bra to my friends is due to the limited sizing and I understand the price isn't feasible for everybody. June 26, 2014
New favorite Ordered this in the camo green. 5'7, 140lbs, 34B (a little on the smaller side). I tried on both a 6 and an 8. The 8 fit around my mid-section better, but was too large in the chest area. I went with the 6 despite being an 8 in most tanks and tops. The 8 also had frayed a little at the seam around the elastic band, which was why this product received a 4 out of 5 stars. The one that I bought had no defects or problems and I absolutely love the way it flatters, not flattens, my chest. June 23, 2014
