dress: [14] Dress originally meant literally ‘put right, put straight’. It comes via Old French dresser from Vulgar Latin *dīrectiāre, a derivative of Latin dīrectus ‘straight’ (from which English gets direct). Traces of this underlying sense survive in the word’s application to the correct aligning of columns of troops, but its main modern signification, ‘clothe’, comes via a more generalized line of semantic development ‘prepare’ (as in ‘dress a turkey for the oven’), and hence ‘array, equip’. (English address developed in parallel with dress, and comes from the same ultimate source.) Dresser ‘sideboard’ [15] was borrowed from Old French dresseur, a derivative of dresser in the sense ‘prepare’.

early 14c., "make straight; direct, guide, control, prepare for cooking," from Old French dresser, drecier "raise (oneself), address, prepare, lift, raise, hoist, set up, arrange, set (a table), serve (food), straighten, put right, direct," from Vulgar Latin *directiare, from Latin directus "direct, straight" (see direct (v.)).

Sense of "decorate, adorn" is late 14c., as is that of "put on clothing." Original sense survives in military meaning "align columns of troops." Dress up "attire elaborately" is from 1670s; dressing down "wearing clothes less formal than expected" is from 1960. To dress (someone) down (1769) is ironical. Related: Dressed; dressing.
