also: どろわーず · どろわーす
noun
drawers; bloomers; knickers
Refers to women's or children's loose-fitting undergarments or old-fashioned gym shorts, typically knee-length and gathered at the waist and legs. The term is somewhat dated; modern Japanese often uses ショーツ or パンツ for underwear.
from English
祖母は昔、体育の授業でズロースを履いていたと言っていた。
My grandmother said she used to wear bloomers in PE class.
昭和初期の女性はズロース
Women in the early Showa period wore drawers as underwear.
Specifically refers to gym bloomers worn in schools; ズロース is more associated with old-fashioned underwear or bloomers.
Borrowed from English 'drawers', with the ズロース form reflecting a common Japanese adaptation of the English pronunciation. The variants ドロワーズ and ドロワース are closer transliterations.
