I live in nyc and see just about everything, but i've never seen this.
must be a midwest anglo/scottish thing?
usually the only men i see in skirts are super femme gay queens, androgynous queer artsy hipster boys, or masculine yet fastidious gay men more of a marc jacobs style skirt.
and bagpipers.
i don't see the point of searching for men with kilts - it's more meaningful to search for "men" on google and count the number of pages until you find one in a skirt
