I finally received my Gc2b binder. I had to order a second because the first was too small, even though I did the measurements. I now have an XS, which is still hard to get on but it’s the right size. It’s a lot more comfortable and easy to breathe than the Underworks binder. There’s also less “Binder lines” that show through. I wouldn’t say it functions better than Underworks, but it’s functions differently. And this way might be preferable to some people. It’s definitely a lot easier to forget you’re wearing a binder with this brand.
