Flow Y Bra IV 4 5 757 759
Good, basic sports bra I saw the WMTM price and bought it. I had eyed this in the store. I normally wear a 8 for running/4way stretch or if it's a tight fit...a 10. This ran small in the 10 when I tried it on in the store and since this is a yoga bra, I was pretty sure the 12 would be best. So, 36C...yup it's fine...mind you...like I mentioned...I wouldn't run in this bra...it's definitely a low key activity bra. Love the mauve. One thing I could care less about...it has built in inserts (cover nipples???). Hoping those don't cause problems later. June 28, 2015
Perfect for a hot summer I love this bra! The mesh in the back provides some breeze and the bra is lightweight, you almost forget you are wearing it! I'm a 34D to 36C, so I DO NOT run in this bra. I wear it day to day and for barre. It is comfortable, cute, and easy to wear. I wear it under plenty of my professional clothes! June 27, 2015
Great for yoga and running errands I love this bra for yoga and as a basic every day bra to wear under my lulu racerback tanks. I am 5'4 125 pounds 32 DD and wear a 6. In the all sport adjustable and energy bras I am a four, however in this bra I need a six to get the proper coverage. This bra definitely is not supportive enough to run in, but I absolutely love it for everything else. Just bought a black and white patterned one in my local store that I don't see online. Can't wait to wear it! June 20, 2015
new sizing is disappointing I have worn this bra for many years. I went to purchase my same size 4 as I have worn for years and the bra is a completely different fit/size now. (And I now see other reviewers are saying the same thing.) It's now much shorter and compact using less fabric in total. And it is a bit tighter all around as well. I am so sad. One of the things I liked about this bra was that it had good coverage for the chest and I could by one of Lulu's tanks that are more low cut and have the bra peak up higher than the tank creating an interesting layered look. Now I feel there is just too much chest showing. Why mess with a good thing? I won't be buying any more. June 10, 2015
Sizing Problems I bought this about 6 months ago, removed the tag, felt that it was too too snug, and decided never to wear it again. I tried it again recently (quite hopeful) that maybe it would fit me this time. I usually range from a size 2-4 in lululemon clothes. I bought this bra in size 6. And even then, it is extremely snug, and makes respiration difficult. I am a huge fan of lululemon clothes, but this one really threw me off! June 8, 2015
Flow Y Bra IV This is the one and only Lululemon bra I ever buy. I love how it fits and is very comfortable. I have it in at least 8 different colors. However, I have noticed that lately they are fitting snugger. I have bought a size 8 for about 7 years, but lately the straps dig into my shoulders and cause a lot of redness, so I have started buying a size 10. Luckily for me, this hasn't changed how supportive this bra is. June 6, 2015
perfect simple bra I love this bra. I use it for everything, from martial arts, running, yoga, cycling. I'm 117 lbs, 5'3", 34B and size 4 fits perfectly. The only complaint is that I wish they come in brighter colors for summer. June 4, 2015
Perfect This is my personal perfect sports bra. I have many different colors. Comfortable, enough support (B cup), and pretty colors. They launder well and the pads are easy to remove and put back in place. June 4, 2015
I believe sizing has changed recently I have worn Flow Y Bra for years. I am a 32D. Always size 6, always fit perfectly. But my most recent purchases (last year or so), the bra seems to fit smaller. They feel snug on me, and the straps dig into my shoulders. So much so that after half an hour or less, I have indentations on my shoulders and back. When I tried a size 8 in the store, the band around the torso is loose, so I know that the 6 should still be my size. I have since switched to the more comfortable 50 Rep Bra (which runs small so I need to size up to an 8). I suspect many Lulu bras are running small these days, and with the diversity in styles, it is no longer a no-brainer shopping experience. You have to try every style on in several sizes to find the right fit. June 3, 2015
go-to bra Love this bra. I wear it under loose or tighter tops and it's been perfect for barre. It's a lot more supportive than it looks. The only thing I'd change is the cut in the front; the cut of the fabric is a little slim. I'm extremely petite with slimmer shoulders, so I'm not sure who they designed the cut for. Still, it's great and versatile and I want it in every color. May 29, 2015
