Hume Gilet

Cannot be auctioned, traded, or bazaared, but can be delivered to a character on the same account.
Cannot be obtained as a random reward from the Gobbie Mystery Box Special Dial and similar sources.

A gilet is a sleeveless jacket resembling a waistcoat or blouse. They may be waist to knee-length, and are typically straight-sided rather than fitted. However, historically, they were fitted and embroidered. Today, gilets are often worn as an outer layer, for extra warmth outdoors.
