Sense of "decorate, adorn" is from late 14c., as is that of "put on clothing." The older sense survives in military dress ranks "align columns of troops." Of males, in reference to the position of the sex organ in trousers, by 1961.

Dress up "attire elaborately, put on one's best clothing" is from 1670s; dress down "wear clothes less formal than expected" is by 1960. Transitive use of dress (someone) down, "scold, reprimand," is by 1876, earlier simply dress (1769), in which the sense is ironical. In Middle English, dress up meant "get up" and dress down meant "to kneel." Related: Dressed; dressing.
