I found this place called dapperQ, which is a style website for masculine(ish)-presenting people that don't have the typical cis-male body. So awesome! Though it's brand new and doesn't have much up right now, I know I'll be going there for tips. And to look at all the pretty pictures of androgynous and butch people :3
Only problem: I've yet found a satisfying way to wear both a collar and a necktie. Currently, when I want to butch/queer it up, I just wear a very small, unobtrusive collar (more a choker or necklace) and then hide it under my shirt and tie. But I always feel a little bit dishonest doing that - like hiding your wedding ring or something, even though it obviously isn't on quite the same level. Does this mean I must resign myself to a necktie-less life? Woe!
