into," as the word is related to O.N. smjuga "to creep into (a garment)" and O.E. smugan "to creep" and smygel "a burrow." Cf. also Ger. schmiegen "to cling to, to press close, nestle," hence M.H.G. verb smucken, Ger. schmucken "to adorn." Eng. smock was common down to 18c., and was emblematic of womanhood generally, cf. verb smock "to render (a man) effeminate or womanish" (1614); smock-face "person having a pale, effeminate face" (1605). Replaced by euphemistic shift
(n.2). Modern meaning "woman's or child's loose dress or blouse" is from 1907; sense of "loose garment worn by artists over other clothes" is from 1938.
