The costume you wear so often you forget it's not your skin.

means The part you play or function you serve — in a job, a story, a family, a team.

from From French rôle, originally meaning the roll of paper an actor's lines were written on — so literally, the script you were handed. The part became the person who performed it: the paper roll lent its name to the performance itself.
