Unraveling thread, not worth the money
Size: Medium, Color: Bright Red
The quality just keeps getting worse, especially the threading unraveling even when I tried sewing it back. 0/10

Breathable, Comfy Fabric with Excellent Support
Size: X-Large, Color: Emerald Green
I'm sixty-three, 5'2 height, and I wear a size 14. I do 3-4 intermediate Pilates sessions each week. I wear black capri yoga pants and a black racer back top of natural fabric, but I add a bit of color with the sports bra. I was very impressed by the fit of this bra; the fabric is soft, breathable, and the bra design offers excellent support. I removed the tag because it was itchy, but I will purchase at least 2 more of these.

Over all great bra
Size: Medium, Color: Black
This is a great sports bra. The material is very soft, very close to aerie offline softness, its padded and very supportive. I gave 4 stars only bc there isn't alot of stretch. I wear a 34 -36 DD. For reference im 5'8 and weigh 165 pounds. I have a muscular build. The bra fits good but getting it over the girls is a struggle dry, I am imagining it will be a two person job to remove after a workout when covered in sweat. That being said the support it provides is amazing so I will buy more. Not a deal breaker. I got the black and bright blu color is just as pictured and doesn't bleed.

Seriously buttery soft and love the fit/color!
Size: Medium, Color: Emerald Green
I am obsessed with the fabric on this sports bra—it really does live up to the "buttery soft" name. I bought it for yoga and lounging, and it’s honestly comfortable enough to wear all day without feeling restricted. The square neck is super flattering and gives it a more stylish look than a typical sports bra. It fits true to size and the racerback doesn't dig into my shoulders at all. If you’re looking for a Lulu-level feel without the crazy price tag, this is a total win!
