Overall great bra I was looking for a bra that wasn't necessarily maximum support, but flattering and still does its job of being a sports bra. This is exactly what I was looking for! It does fit quite small, so if you're looking for a similar supportive/tighter fit I would go one size up than your usual at lulu, but if you want a more comfortable fit I would advise going up 2 sizes. It looks nice under t-shirts and is great for multi purpose stuff. I'm a 34D/32DD and a size 8 fits me quite tight but well. December 8, 2014
disappointed I was so excited to get this bra cause its really cute. I ordered a 12 it fits like a 8.. extremely small and uncomfortable. So disappointed. I am never one to complain about Lululemon because I love their clothing, but this bra is definitely something to complain about. November 24, 2014
cute bra? but causes back pain I loved this bra so much that I bought a second one as soon as the first one arrived. It's a great everyday bra, and doesn't look like a sports bra under work clothes (huge plus!). Black is easy to match with my wardrobe. The material is comfortable, and the stitching good quality. No underwire. All good things. The downside is back pain, especially as the day goes on. I NEVER get back pain under my bra straps. But as soon as I swap out this bra at the end of the day, the pain disappears. During the day, I catch myself lifting the straps up to get the weight off my shoulders. I'm a **small** 36B, and ordered a size 8 instead of my usual 6 based on the reviews. The top part fits well but maybe the band at the base of the bra doesn't provide enough support? I've never had this issue with any other Lulu bra. Overall, I think it's a good bra (assuming it fits you properly). It's just not for me. Disappointing... November 17, 2014
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
