I'm on the bigger side but with a relatively small chest and this was a really nice find. It's a similar sizing to underworks but much more comfortable, especially around the armpits and stomach, and roomier than GC2B. The compression is medium/low. The fabric is softer than other binders and more flexible and it breathes better.
I'm a 44" chest (narrow rib cage, large cup size), and am swimming in the XXL, but it actually works as a cute crop top, and still provides a few inches compression, so I'm keeping it and getting a smaller size as well.
This is the MOST comfortable binding I’ve ever worn, just from the material and fit. If you’re using underworks sizing, though, I’d recommend going down a size from what you measure because this one is pretty loose.
I bought this binder for my teenager. I loved the fit & quality of this binder. My teen says it's very comfortable & it's stood up to many many washings. We like it so much I just ordered 2 more.
This binder is incredibly comfortable, though I ordered based on measurements taken for Underworks brand (which work amazing but cut into my underarm/sides). This binder is not as tight/flattening. Will try a size smaller.
