very similar to gc2b in that it is very stretchy and flexible at the back with a panel of compressing, non-stretchy fabric in the front. i prefer this one over gc2b, because the fabric feels softer and i think the contour looks more natural. i am a 38DD and the large size fits me really well! it is a little tricky to get on if you don't have the most flexible shoulders in the world lol but it is very comfy and doesn't feel restrictive once on. offers great full coverage, and i like that this one is not a t-back so the neckline is wider. the only thing is that the beige is quite dark, i am on the olivey side of white (and kinda tan atm) so it isn't as much of an issue as it would be for someone paler. high quality construction, very comfortable, and well worth the price. so happy to be supporting a small, trans-owned canadian business!
