Cute but not very supportive
Size: Large, Color: Navy
This bra is cute but it’s not very supportive. I’m a 34DD and it gaps on the sides and the straps are too long even though I have a long torso. I’m not even sure that I’ll wear it low impact activities, probably just day to day wear.

Cozy for Sleepwear
Size: XX-Large, Color: Emerald Green
I bought a plum thermal union suit, but it has actual buttons. So I bought this bra, so I could leave some of the top buttons undone for quicker trips to the bathroom while also giving a nod the color combo of the Quetzal bird.

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.
