'apparel' originates from Old French, specifically the word 'apareillier,' where 'a-' meant 'to' and 'pareillier' meant 'to prepare or make ready.'

'apareillier' transformed into the Middle English word 'apparailen,' and eventually became the modern English word 'apparel.'

Initially, it meant 'to prepare or make ready,' but over time it evolved into its current meaning of 'clothing or attire.'
