'attire' originates from Old French, specifically the word 'atirier,' where 'a-' meant 'to' and 'tirer' meant 'to arrange or equip.'

'atirier' transformed into the Middle English word 'atiren,' and eventually became the modern English word 'attire.'

Initially, it meant 'to equip or arrange,' but over time it evolved into its current meaning of 'to dress or clothe.'
