Absolute FAVE!
Great fitting, comfortable and separates the girls nicely (headlights still show, however). I normally wear a 34DDD, which fits great, although the band is on the tight side. I can also wear a 36D which offers a wee bit more comfort. This is my every day, go-to bra. I wouldn't use it as a jog or heavy exercise bra - it has some jiggle. I love Amazon's price for Wacoal. You can't find this low a price anywhere. I purchased 4 of them in different colors. Highly recommend.

Best bra Ever!
I'm a 34 DDD. I can never find my size, and when I do find my size I'm either dealing with quade boob, falling out you the support is so dissatisfying I consider going without completely. I will Never buy a different brand of bra. I can't say enough about the fit comfort and support offered by this amazing bra!!

Best sports bra for large bust
This is my favorite sports bra, it is the most comfortable bra I own. I’m a DDD bust and this bra gives me all the support I need. I have other Wacoal sports bra without underwire and this bra is just as comfortable as the wireless and gives better support. Bonus you can crisscross the straps to wear with a racer back top. I hope they get more colors in the future. Added note I ordered two different colors and the nude color I received was not the same bra as pictured, it had very thin straps and ran very small.

No uniboob but not full support.
I am very large busted (DDD) and this was true to size. I'm usually a Lane Bryant or nothing kind of girl. I took a chance on this bra because I was looking for something to wear backpacking. This bra is comfortable, though much harder to hook in the back than my regular bras. The material is very soft. It did have a slight chemical smell upon opening but I suspect it will come out with a wash. As for support, this will be a good day to day bra and I will probably wear it when I go kayaking but not for running or hiking. It lifts the girls but won't keep them from bouncing around with heavy activity. I dont want a black eye. Bonus points for no sports bra uniboob though.

Low to Medium Support for 34G
This year, I've been on a search for the perfect sports bra to start running. I wear a size 34G, and obviously, I can't buy anything off the rack. The S/M/L sizes are terrible because they are either too loose around the rib cage or don't have enough coverage for the ladies. This bra doesn't have that problem. Unfortunately, though, this bra didn't provide the support it boasted. I jumped up and down, and I definitely felt my girls jumping up and down with me. Painful! If you're looking for a yoga bra or something you can wear to lifts weights, go for it. Otherwise, choose something else. I recommend Wacoal's Sport CONTOUR bra. It's magic for us big-busted ladies.

Great support and very comfortable in the straps and around the chest
I usually regret buying a bra on line and dont do it often. I am pleasantly surprised a this one! I have to have the underwire for the support as my chest is not firm enough to hold itself up! The wire is not really noticeable. The material is 2 layers and I figured the nipples would stick through and show but it hugs just right and doesnt look like I am shining the world!!! Really pleased with this bra.

Finally one that fits well!
I am petite and heavy breasted. Finding a truly supportive bra is a challenge. This one holds me in place and is comfortable around the band. The straps are wide so don't dig in like thinner straps do. I wear 32DD and use an extender to add 1/4" to the band. I am 5'1" and weigh 133 lbs. I like this so much I purchased two more.

Bra Strap Broke
Just purchased this less than 90 days ago I work out everyday but switch between this and two others it’s a good fit and comfy but pulled it out of the drawer today and the strap broke as I was putting it on.
H**!
Love this bra <3
The bra is on the more generous size, so if your in between band sizes, definitely size down. Not max support, more like medium + for large chests, but definitely comfy and kind of cute. Also gives a very nice shape. Great for weightlifting and everyday, but not sure I'll do much running in it.

Gran soporte
Soy talla 38G, me gusta mucho wacoal, es mi marca favorita porque maneja una gran variedad de tallas y justo la mía no la tienen otras marcas, la más cercana es 38DDDy no me ajusta del todo. Este bra tiene excelentes materiales, como todos los wacoal, da mucho soporte y moldea muy bien. Lo volvería a comprar.
