costume
Usage Note
Costume means a man's suit (jacket + trousers) in everyday French, as well as a theatrical or fancy-dress costume. Un costume trois pièces is a three-piece suit. For a woman's suit, French typically uses tailleur. The word is a false friend for English speakers who might expect it to mean only a stage costume.
Examples
"Il porte un costume gris pour l'entretien."
Natural Translation
He is wearing a grey suit for the interview.
