Long story short, the binder I bought a few months ago ended up being way too small. I wore it about twice, but that's it. And since then—and sometime before that too—I've been using the sports bra and vest method of binding, however recently doing so has been very painful. It's true that I've been doing this since about October now, but I read it was relatively safe, and I really don't have big a chest at all. My ribs hurt while and for a little after I bind like this, but it's mostly my breasts that are killing me. It could be hormones, but I doubt it, and frankly put worried that I won't be able to wear the new binder I ordered. Could anyone help me out?
