There are lots of other cultures where men where some version of skirts, and it looks fine. In South India, lots of men both Indian and Western where lungis and it looks fine
This looks like a man trying much too hard to be non-binary or gender-free something or the other. It's too deliberate to be a natural look. If I were young again and dating I would not be attracted; I'd find him embarrassing, unlike a man in, say, a lungi
Well all that proves is presumably your social conditioning that some clothes are suitable for men and some are not.
Despite the strenuous attempts by some posters to dismiss this as nothing out of the ordinary you would look long and hard to find a man in western society dressed like this.
The mantra on here is "wear what you want" and "clothes are for everyone".If you believe that then it is completely irrelevant whether he is breaking down gender roles.
The responses on here show that these mantras are really only paid lip service to when presented with someone like him. I can't say that surprised me at all.
And of course there is the usual narrow - minded attacks on anyone who wears high heels, such as the absurd suggestion that no women working in an office would wear high heels and that women "totter" around in them. I'd love to see the posters who made these comments say them to the faces of the women I work with.
