Today it’s very windy, chilly and cold outside. In winter season cozy and warm underwears are sold at every store in Japan. Sometimes we call them "Baba shirt" in Japanese. I guess the word "baba" comes from "obaba"(old woman). I can say maybe it’s kind of Japanese slang. It indicates cozy and warm underwear but usually only old women want to wear those things but many women wear them in winter. I wonder warm long johns for women (panties long leg) are only sold in Japan because I’ve never seen them in Canada or Colombia. Actually they don’t look so elegant. They really nice and comfy though....
