I’m 69 and I’ve seen five. Although three were men wearing something like a kilt. One of them had prostitute-style fishnet stockings. Today I met a man who I at first thought was a woman. But after spending time working out an order/shipping problem I realized this woman had much more masculine features than me; taller, broader shoulders, thicker, larger hands and forearms and a very thickly haired upper lip although the hair itself was wispy. The breasts looked tacked on.
I’ve seen a couple of other guys in kilts, too. Kind of weird in the USA, but they were both manly guys. Maybe they were on their way to Scottish Games and the Caber Toss.
One way you can tell is by checking for an Adam’s apple.
