Quality Material, Comfortable Fit
Size: Medium, Color: Emerald Green, Size: Medium, Color: Emerald Green
I often have trouble with sports bra bands feeling too constricting (for size 34C), but this one was comfortable enough to wear right away and I can tell it will get comfier as I wear it. I am 5’7, 130 lbs and bought a medium. The color is vibrant and the material feels high quality. Straps are not adjustable but that hasn’t been a problem up to this point.

Good price, does the job
Size: Large, Color: Emerald Green, Size: Large, Color: Emerald Green
I love the way this fits. I’m probably a C cup on a good day and just under 200 lbs. I wear this for my workouts (elliptical and weight lifting). It stays in place, has kept up in my chaos washing, and is super cute.

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.
