I've always known I would not pass. Anyone giving me a second look could probably tell, but not very many give that second look. From the perspective of being dressed up, I primarily dress to please myself and feel confident. Since I can't control what someone else will think, I can only try to not look offensive, otherwise that's their problem.

My interest was more of an onlooker perspective. Either there are very few cross dressers out and about in my area or I am terrible at noticing.
