I know a man (cis and straight, he never had any doubts about his gender and orientation) that owns several skirts. He often wears them around the house - because it's comfy and stylish, not because of some weird fetish. The skirts were sewn to his measure from a fabric he chose.
He now plans to start wearing them outside the house, i.e in public. Is it a good thing from a feminist point of view in your opinion?
A skirt is just a tube of fabric. If he's just wearing a tube of fabric that offers plenty of coverage like a kilt I'm fine with that. If it's an obvious fetish like a mini skirt with heels and shaved legs I'm not a fan.
