Just wanted to drop in and point out that I think that guys in skinny jeans are mighty hot.
Of course, it does lend you a bit more of an androgynous look, which may make you less passable, but it probably depends on what people in your area are used to. I live near the San Francisco Mission District, which is hipsterland, so nobody notices a guy in skinny jeans.
I wear skinny jeans with an oversized t-shirt on most days now, which is a nice androgynous look that can be femmed or butched by what shoes you're wearing, what's on your shirt, and by what kind of jacket or hoodie, etc. you wear with it. It'll probably look good, but it probably won't help much with your passing. Then again, I don't worry much about passing nowadays - I like coming off as androgynous.
