Flannel shirt is fine, but flannel pants are pajamas are only for wearing inside. A T-shirt made of jersey material is fine to be worn out, but thin jersey pants are pajamas and should only be worn at home, so says conventional wisdom.
But, if shirt is made of pant, then it’s nice/slightly fancy. Denim shirt? Nice, durable, suitable for a restaurant.
I don’t know if this applies to women’s fashion, as it seems to have very different rules to men’s wear
What? Have you never seen the Mighty Mighty Bosstones? You can definitely get legitimate (plaid) pants. Probably not flannel not sure that matters here if the pattern is what you have in mind.
Not sure thats the same though, I think they’re talking about the material, which is generally not warm (windproof) enough to have as outside pants.
That’s a good point. Flannel would probably not wear well as pants, either. I’ll simmer down 🫣
