It's alright
It's best you order a size up and it's hard to get on but once it is it's comfortable,you breath fine and binds amazingly

Ill compare the gc2b binder and underworks for people like me who are wondering if they should get it. I have worn the binder for almost a week now and it's usually on for more than 10 hours (which I definitely do not advise, I have severe rib and back pain from that) First off- shipping was extremely fast, I live in southeast Europe and it came in around 5 days (had to deal with customs but that's because I ordered from the American Amazon like an idiot). You receive what you ordered, an underworks branded binder with the size and colour you chose. The binder itself is made out of some sort of rougher, mesh material, way more rough than the gc2b and slightly longer (I find that more comfortable). It was kind of itchy the first day, but I quickly got used and it doesn't bother me anymore. The shoulder straps and the neckline are more discreet, they're farther away from where your shirt neckline would be, the gc2b are really far up and could be seen under most of my shirts. The straps cause some tension and therefore my shoulders hurt ( kind of like I have sore muscles but that might just be me). Some people say the bottom of the binder rides up, that doesn't happen to me but everyone has a different body so take everything I write with a grain of salt. Lastly- the binder is, from what I can feel, a bit tighter than the gc2b, it does bind better (i have worn the gc2b one for more than a year and it might have been slightly stretched). But since its tighter it also causes more pain. I wear the binder, usually, for more than 10 hours, my back and rib pain has increased and there is added shoulder pain, sometimes it's almost unbearable. Otherwise the binder is perfect, I love it and I will definitely order more.
