decent (adj.)
1530s, "proper to one's station or rank," also "tasteful," from Middle French décent, or directly from Latin decentem (nominative decens) "becoming, seemly, fitting, proper," present participle of decere "to be fitting or suitable," from PIE *deke-, from root *dek- "to take, accept." Meaning "kind, pleasant" is from 1902. Are you decent? (1949) was originally backstage theater jargon for "are you dressed."
