Seeking Recommendations for a High-Quality Binder

I’m 4 years on testosterone and pass more so than I used to but still get misgendered every now and again. I think it’s due to my chest not exactly being the most flat even with a binder? I have a top surgery consult in September and they said I’d also have to wait 6 months after the consult for my surgery. In the mean time does anyone know where I can get a really good compressing binder? Like for larger chest that are not gc2b cause the last couple years in my opinion haven’t been the best quality? I’m not sure. But the stitching isn’t as good as before. But yeah just trying to find a website that a bit different than gc2b this time. Thank you! (Pls nothing from Amazon lolol dangerous)
