I posted a thread for this but probably should have posted here, so I'll just copy and paste, and apologize for making a useless thread.
Sorry if this has been answered before, there's so many topics on binders that I'm kind of lost.. So a while ago I read a post on tumblr recommending this binder for crossplay,
I measured myself and was surprised because I'm only about a C cup, but needed at least the second largest size. I bought it, and it's just too tight, at first it doesn't feel too bad but after wearing it for 10 minutes and taking it off, my chest and ribs were hurting quite a lot. I'm not really a big girl, I might not even be a C cup(to be honest I don't wear bras so I don't know), so I was really surprised that the second largest size was far too small for me, I can't imagine larger girls wearing this.
Did I just buy the wrong one? I really don't know which one to get, and they're quite expensive since I'm buying them from Australia so I don't want to waste money on another one that doesn't fit.
