Spy's Tutor

Wondrous Item - Uncommon
A set of unassuming clothes, protected by magic from age and damage even as the seams appear to pull apart with a sturdy tug. The topside of the fabric seems to be coarse, sturdy workclothes, but flipping it reveal finely woven linen; turning it back again shows silk, again soft leather suede, begging to be stitched back together in new patterns.
When a creature spends a long rest wearing the Tutor, until the end of their next long rest they gain one skill or tool proficiency, chosen by the appearance of the Tutor. During a long rest, any creature may attempt a DC 15 Dexterity (Tailor's Tools) check to re-pattern the clothes into the outfit or uniform of a particular profession, on a success changing the proficiency granted by the Tutor to a different proficiency appropriate to the new appearance. If the check is a natural 1, the garment falls apart, losing its magic.
