Rated 4 out of 5áby Flow Y Bra iv - pretty good I purchased a Flow Y bra iv in ?ziggy snake butter pink black/butter pink? from wmtm in size 6. I never see bras in my size on wmtm in a version I like. It was a gamble, however. I own other LLL bras (in size 6, mainly FTB & FTBW) and have tried on Flow Y's in the past, but never felt interested enough to buy one. The reviews also speak to inconsistency in sizing so I was actually prepared that it may not fit properly. This Flow Y fits me pretty well. It?s solid support but not constricting. I'm a 34B (5'5" 125 lbs) and it provides plenty of support for me for running. I've worn it on a few runs, long walks and casually. I was happy that I mostly forgot about wearing it each time, meaning that I found it quite comfortable. One hot day when I did a lot of walking it did start to cause itching at the bra band. I thought it was a combination of skin sensitivity and the heat until I wore it for a Fall run recently in much cooler weather. I was not overdressed or overheating and it became fairly itchy towards the end of a 10K. When I took it off there was some redness in the front where the band rests. It was not intolerable but the increased irritation obviously wasn?t reassuring. This Flow Y also does not have a circle mesh interior (I don?t know if they sometimes do?), which I find comfortable and non-irritating ? also more breathable ? in the other LLL bras I wear. The bra body is also higher than I am used to in comparison to FTB and FTBW bras. I think the issue for me in this particular version is the materials (interior and main material) in combination with more coverage. It may not be the ideal bra for me but it has not put me off another potential Flow Y purchase or continuing to wear this one (just not for longer runs). Aiming to be helpful, I have attached pictures showing how the bra fits on me. Happy running and any activity you do! November 2, 2015
Rated 2 out of 5áby Style modified? I have two of these bras from 2012 in an 8 and I love them. I recently purchased a new one in a 10 and it almost feels too small. Has this bra changed since 2012? I'm disappointed because I've worn it a few times hoping I'd learn to love it, but it just hasn't happened. Sadly, it has a home in the bottom of my drawer. October 28, 2015
Rated 5 out of 5áby Comfy bra for everyday use and relaxation! This bra is super comfy! I am a size 36C in normal bras and I was a little worried that this bra wouldn't have enough support, but it does! I haven't worked out in it yet, but it's perfect for everyday use and lounging around. I definitely recommend it! October 22, 2015
Rated 5 out of 5áby Great for B cups I'm a 34B and this bra works really well for me. There hasn't been any pinching or bulging with my usual size 8, and at the same time I don't feel like the bra flattens me out. Great product, and I'm sure it will last a very long time. October 13, 2015
Rated 1 out of 5áby Pilling I would recommend this bra to a friend if it wasn't pilling so much! I wash it accordingly to what lulu says but it is very bad. Its so disappointing from lulu because they have such amazing stuff October 10, 2015
Rated 3 out of 5áby 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 5áby 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 5áby 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 5áby 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 5áby 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
