So comfy!
It’s very comfy and I like the racer back better than the regular one because the straps don’t fall off your shoulders

How Does it Fit?
What Size Did You Order?
sizing is small
the material is soft, smooth, and stretchy—lives up to the tna butter name. i had no problem with the style or feel of the bra, however, the sizing is way too small. i own other tna butter items but they're proper tanks and rompers, and they're either xs or s. this was my first time getting a bra. since the item is just for the upper body (and a mini version at that), i should've sized up to a medium. xs didn't feel tight, but it didn't even reach to the middle of my chest area and showed my back fat. i had to return the bra. as long as you know your size, the bra is perfect. my measurements: 5'2, 32b-27w-35h, 112 lbs. i ordered black in xs.
