Male bodies are not as heavily sexualised as female bodies in our society, so a natural result is that men’s fashion are typically modest (ie not designed to look ‘sexy’). Women are visual though. Pop psych likes to say that women are seduced through the ears but that’s honestly just a huge generalization. We are just not as visual, but a good deal of us lust after men. Increasingly so, since everything now is sexualised (including men) which can explain why a significant portion of women watch porn now. Think of men in Saudi Arabia vs men in Hawaii. They’re conditioned to find different areas of the body sexy. An ankle is not scandalous in the states, but go to another culture…
However there are certain types of fashion that can be immodest (codpieces) lol.
Anyway, men can be immodest. From what I see as a young woman, men tend to be immodest by the things they post rather than what they wear on a night out. Nobody wants to see your gym pics on Instagram every day, Jack!
