Well unless you have androgynous/feminine features, it'll be totally gross. I guess its mainly due to the way I'm (most of us are) conditioned by societies' thinking being the mindless comformist zombies that we are.

On another note, some asian girls actually seem to prefer androgynous 'pretty' guys to the masculine big-jawed or tough/macho-looking ones. This seems to be especially common in Japan's pop culture, and the line between their male's and female's fashion thins.

Hopefully in future, us guys would have more fashion freedom too than just boring printed t-shirts or shirts to go with some jeans or pants...etc...
