Yep, I have shorter ones for more casual outfits and full length for dressy events. They never seem “costumey” when they go with the overall look. I’m a woman in a metro area though.

I bet men could, too, with a suit on a formal occasion.

I disagree. I think some men could pull this off, but it would mostly come across as cartoony in most circumstances. Even 3-piece suits are seen as too formal/old-fashioned by people.

Where I could see cloaks looking fashionable and natural is in milsurp/gorpcore inspired outfits. Something like This cloak is pretty damn interesting and would look just fine On this outfit Or this one

I have a wool plaid cape I got from a woman's estate sale but it isn't necessarily gendered, though as a man I haven't been brave enough to wear it outside of the house yet except to a Burns supper where I got a lot of compliments. My coworkers are used to seeing me wear it on video throughout winter

Edit: after some googling it may be a cloak and not a cape since it is full length. I wear it as a sweater replacement
