Having known too many women who like lingerie on men, I am going to say lingerie.

I think Marky Mark demonstrated in the 90s it is the boxer brief.

Man lingerie ! It is less diverse, harder to find, but it exists and can work the same purpose

I don't like men in sexy underwear, but not that into lingerie on women either.

Guy clothes that I find hot are white cotton button up with rolled up sleeves, jeans that fit but not too tight, kilts, suits can be great especially on lean guys, tighter jeans are also good on tall and skinny guys.

A cock sock that makes your dong look like the trunk of an elephant or something.

Also Speedos.

I don't think there is an equivalent; as women are much less visual creatures than us men. The closest thing I'd say is muscles and a good physique.

A nice jock strap/cup underwear.

Lingerie

Suspenders. .

Grey sweatpants. Love seeing that thing swinging and jiggling about.

My fiancée is a big fan of my kilts

She has sent this to a few people she knows who appreciate a bloke who is not afraid to wear a skirt

Abs, confidence and anything tailored to fit

Wearing womens lingerie

Late reply, but I've had more than one ex who liked me in my big stompy chainsaw boots and nothing else. Found out by accident when I put em on mid session to pop out for a piss. When I came back, she was like "Wow, keep the boots on!" I tried them with my next partner and she had a similar reaction.
