home sweater

A sweater meant only for home wear. This may be due to it being really old or tattered, but the comfort and/or good memories prevent you from throwing it out/donating it. It is probably one of your favourite sweaters.

Ben: I can't, I'm wearing my uber-comfy, uber-ugly home sweater!

Sarah: Well change and get out here!
