IMHO - you are who you are, regardless of your outer appearance / presentation. As so many others have said already, orientation doesn't change based on clothing. Perhaps willingness to allow yourself to accept it does when dressed.
I know that for me, I too thought for a long time that orientation and clothing choices were interconnected. But, as has also already been pointed out, IF the desires are acted upon then at some point the outer persona of the clothing is shed. Once I realized this for myself, I was able to disassociate orientation and dressing. I am simply me. I dress because it is something I have to do. My attraction to women or men is also something I can't control, it simply is what it is. I can only control my actions - and as I have a GG SO, I live hetro. But I'm still bi (and yes, she knows I'm bi).
