Define Bra 4.1 5 17 17
This bra looks very comfortable and pretty, but I ordered it in my regular size 4 and I couldn't even come close to putting it on. I would say size up at least a size, maybe two. Just FYI, a size 4 bra when laid flat measures only 10 inches wide (for reference, the 50-rep bra and stuff-your-bra are both 12 inches wide in a size 4) and the material is NOT very stretchy.

Best bra I have ever owned! No cutting in at the neck, adjustable straps, super comfortable, only wish it was available in more colours. September 20, 2014
good bye Victoria secret! Could you imagine if this bra came in SKIN COLOURS?! I would do anything to be able to wear this bra under a white tee shirt!! Im a 32DD, yet want to wear all the flat girl styles out there. I wear this bra to hot yoga, hiking, running and If it came in nude id wear it everyday. helo me say goodbye to Victoria secret!! i don't want to go UP cup sizes i want to go DOWN cup sizes!!

Love this bra! It is so comfortable and fits like a second skin. I recently had an accident and have very limited use of my right hand, which makes putting on a real bra next to impossible. I have been able to put on and take this bra off with one hand. I bought it in a size 12 (I'm a 38D). Hoping that Lulu comes out with more colours soon as it's a great everyday bra, and has a super cute cut (which is important for busty girls too!). September 7, 2014
Perfect Bra! This is the most comfortable and flattering bra lululemon has ever made! I'm a size 32DD and usually wear a lululemon 8 but I had to size up for this bra. Once I got that size I was amazed at how comfortable it was and how gorgeous the bra is! I had to buy both colors and I wish there were more color options! I'd love it in inkwell and possibly a nude color. Though this bra is not supportive enough for all activities such as running, I find it is PERFECT for everyday wear and for pilates and yoga.Now that I have this bra I don't think I can ever go back to wearing normal everyday bras!

Does not define I've been searching and searching for a sports bra that does not crush my boobs into a flat pancake so that my cute workout clothes look cute after my workout, too. I was sooooo hopeful that this would finally be the one. Alas, it is not. The pictures seem to make it look like there is some actual separation between the girls, but they are actually just as flat as if I were wearing a Power-Y, Energy Bra, or Free to Be Bra. It's too bad because the material is nice and a little silkier than the others, and the cut is cute. However, I don't need another smushy bra, so for $58, this one will have to go back.

Soooooooooo comfortable and flattering The define bra is amazing! Yes, it seems small before putting it on but i found it to be tts: bought a size 6 for my 32B, 5'2", 119# bod. I'm short waisted/petite in height and, therefore, appreciate the adjustable straps. The define bra is so comfortable! I've worn it for loooong days traveling and love that the fabric is sweat-wicking and so comfy. Cup inserts are a must for me with this bra/fabric. More colors, please! :) August 22, 2014
Love this bra sooooo much! I bought this bra at my local store in Calgary, AB, even though it says online only? Anyway, I grabbed a 4 since that's what I usually wear. I tried on the 4 with cups and they just look awkward. The 4 was too tight anyway, so I tried a 6 instead, with inserts. This bra fits beautifully, even though it's pretty small. I was so surprised that the 6 fit me, since I have an itty bitty chest. *REFERENCE* I'm 5'3, wear a 34A normal bra, and weigh about 110 pounds August 22, 2014
So comfortable! I came across one of these bras in my size at my local store (even though it's apparently Online Only?) and the fit was amazing. I can see why some may find it fits small, but I got it in my usual size 6 and it fits me well. I'm a 32D bra size for reference. It's super soft, comfortable, and flattering. Only issue is I forgot to ask for cup inserts at the register. I only paid $19 for it, so can't really complain! August 22, 2014
LOVE this bra! Yes, it was tight, and a little hard to put on at first, but after wearing it for a bit, it feels like it molds to my skin. Bonus that it doesn't dig in. I pretty much only wear sports bras (hey - they're comfortable). This bra gives a little more definition (less uni-boob) than other sports bras. I will be buying more! I am a straight lulu 4, and I feel that even though it is tight at first, it fits true to size. I am also an A/B cup. August 19, 2014
