Tailoring is a Corporalki ability to change a person's appearance. Tailors were once considered rare and special though in Ravka, tailoring is now taught to all Corporalki students of the Second Army. Genya Safin was a Tailor and was considered a low-level Grisha who served the Queen of Ravka.

Tailors can also change a person's eyes and hair if they have the right material, or take away or give a tattoo.
