Verb: to dress or clothe someone in particular clothes. Noun: plural of attire; multiple sets of clothing or outfits.
From Old French attirer (to prepare, equip, dress), from à (to) + tire (equipment or turn). The verb entered English in the 14th century and remains in use today as a somewhat formal word for dressing.
Even though 'attire' is considered fancy or old-fashioned today, it's still used in formal contexts—'business attire' is how invitation templates tell you what to wear. We've kept this one word for formality while dropping the rest.
