I'm not sure - as an "armchair philosopher", I think about such things frequently. I used to walk through my neighborhood every morning to catch a vanpool. I'd frequently encounter a group of 3 or 4 older women. The first couple of times I was in pants - I could tell they were nervous, I'm a big guy, with beard and long hair. Then they saw me in skirts, and were way less scared. After a couple or 3 more times, they'd stop to talk to me. I think it may be that the skirt somehow gentled my appearance in their eyes. *shrug* (???)
Then there's the whole "self confidence thing" that I guess they find interesting. One of my dance teachers told me recently that she gets a lot of interested questions from women. And I've had experiences with what I call "feral women" at performances at times. They make their interest known in no uncertain terms - which makes me limit my contact with audiences when not on stage. They don't seem to care that I have my wedding ring on, although perhaps that stops some. I tend to stay in the safety of my dance sisters.
My wife and I were in a "high zoot" restaurant once upon a time - I was dressed to the nines in an ankle length black skirt, a flowey shirt, hair "down but done" with a tikka-like forehead piece of jewelry that anchored in the hair (Similar to the one I wear with the Brolita costume that you've seen pix of), nice earrings, full makeup, blah, blah. Table full of older women nearby who were celebrating one of their number's birthday - and were VERY interested in me when I walked by to use the "facilities" (and yes, it was the fucking MEN'S room where I belonged!) Anyway, we finished up and were leaving, so I stopped off at their table to ask "So, whose birthday is it anyway?". BUSTED! The look on their faces was priceless! Long story short, one of them propositioned me right then and there - wife by my side be damned!
