Rated 3 out of 5 by Flow Y Bra (3 different colors) I have purchased this style bra on 4 different occasions in the hope that the fit will be right, the next time. This bra is so incredibly and ridiculously tight and I have a small rib csge and bust. I am a 4 in most all tops except ones with built in bra in which case I wear an 8 because the band is always so TIGHT?! I love the style of this and the prints but I just had to return the Pretty Plume in a size 10! (I am a 34 B) because it was still too tight and totally flattened out my bust. The bra band sizings are so inconsistent. Why? Shame. September 26, 2015
Rated 1 out of 5 by Be wary... This bra is wonderful...usually! I recently purchased this in a different colour, (diamond jacquard slate), expecting it to be the same as my other 3, and it was so tight and uncomfortable. It is very disappointing the consistency is not there. For the price of lulu gear I expect more. The same lack of consistency happened when I purchased another long sleeved tee in another colour a few weeks ago. Very disappointing when I now have to drive an hour to a lulu store to make any purchase, to ensure quality and consistency. September 21, 2015
Rated 3 out of 5 by snug I am someone with a tiny frame especially my upper body, so I found it odd that when I put this sports bra on in my normal size, the elastic was extremely constricting. I hadn't gained any weight nor had I needed to change sized in any of my other lulu sports bras. But for whatever reason, this seemed to run very small. Otherwise, it provided great support as I do not have a large chest. September 9, 2015
Rated 5 out of 5 by One of the best sports bras I have this bra in two different colors, and I love it. It is very comfortable and good for dance. One of my favorites that I own! It gives enough support for me since I am a 34 A. Not sure how it would be for a bigger bust, but great for smaller ones September 2, 2015
Rated 5 out of 5 by Holy Grail Being a barely 32B, i've always had problems with my bra sliding up when I work out. I've tried many high named brands to bras from target and this one stays put! I love how there's padding so when I get a bit chilly (you know what I mean ladies..) it's a good coverage. I mainly do powerlifting, crossfit, weightlifting, and cardio every here and there and this gives me the best support as well as the "cute" aspect for those days that I do yoga or it is too hot that I would just wear my sports bra. Definitely recommend. August 25, 2015
Rated 4 out of 5 by Comfy but not for the curvy As someone with a larger bust (D cup), I've often searched for a sports bra that will be comfortable but also keep me from falling out when I exercise. This definitely wasn't it, but I'm giving it 4 stars because I think it would be amazing for those with a smaller bust. The fabric is really soft and the band feels very secure without ever feeling tight - which is awesome. My problem was that there just wasn't enough fabric for my chest, rendering it useless. Alas I bought it from WMTM on a bit of a whim so will have to find someone to give it to. I think that if the size 12 did have more fabric, the straps would definitely be good enough for light to moderate exercise. August 21, 2015
Rated 2 out of 5 by material molds after few washes I was SOOO love with this bra; it was my go-to as I don't need a ton of support and cherish the optional padding. however, after a few washes, I noticed the material started to mold for some reason. I immediately take out the bra after wash and air/hang dry it and yet, all my flowY bras molded. not sure what they use in terms of the fabric but more and more, my satisfaction and expectations of quality are declining with lululemon products. also had to take SEVERAL crops back b/c the seams would just fall off!! Lululemon.... please stop skimping on quality of fabric and assembly. August 20, 2015
Rated 5 out of 5 by buy two This is my favorite bra. I forget I'm wearing it when I run. It's the one I wear for races because I never need to worry about it, it holds everything snug and it's just really comfortable. If you don't like bras with thin straps, I would still give this one a try because it's the best one I own. Compared to the classic thick strap racer-back sports bra you see so much, this is much less constricting, more more breathable and more supportive. I love the mesh in the back. It's not just for flash; it helps me breath so much when I'm sweating. Don't knock this bra until you try it! I wouldn't change a thing. August 18, 2015
Rated 5 out of 5 by Perfect medium I love this sports bra because it doesn't feel as constricting as high-intensity sports bras - but still provides much needed support. (I'm a 36C) I am definitely going to buy more of these in different colours. August 11, 2015
Rated 5 out of 5 by Best Lulu Purchase The Flow Y Bra is for sure a favourite of mine, the fit is so comfortable and not to snug but just providing the right amount of support for everyday activities. I personally use mine when I'm out running, coaching gymnastics or even just out picking up some groceries. This bra fits true to size, my favourite part is that the straps do not dig and I also love the mesh on the back. I would recommend this bra to friends. For reference I am a 32D and purchased this bra in a size 4, it doesn't provide too much coverage as I am a little more busty but nothing to major. August 11, 2015
