This topic would have more crediblity if the MtF CD community would wear womans clothing sans the wigs, makeup, breastforms, and other accessories or the woman wearing "mens clothing" would put on fake beards, bind their breast and put a sock down their pants. But that isn't the case. No CDers are trying to look like a woman while a woman is still being her feminine self even though she may wear what is traditionally men's styles. It doesn't matter it the pants and shirt she wears was cut for a man or cut for a woman she is not trying to pass as a man.
There are very few woman who do try to look like men. They are know as Drag Kings and I was half surprised not to see a sister message board here for them. I would venture to say if you were to talk to FtM CDer they would tell you they have as much difficulty as us
