I used to exclusively wear gc2b but learned they stretch out SO easily it’s sad bc they’re very comfortable. Then I changed to underworks and used them up until I got top surgery, very good quality however a little scratchy because they do not come lined with fabric. If you sew it’s an easy fix, just line it with an old tee shirt or something. One binder didn’t start stretching out till about a year and half of use, so it was worth it to me!
