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
An old word for “towels”. The “linen closet” was where the towels were kept, and the few times I heard “linens” the people saying it were referring to towels.
You know what, that makes sense. It’s one those things that you don’t hear everyday so you have no reason to investigate the meaning.
