This is an artist (from Pacific Northwest, I think?) altered Levi's denim vest.
Appears to be a Levi's denim jacket with sleeves removed.
White with light linework reminiscent of Agnes Martin puts this firmly in Art Punk/ Art Metal territory.
Tag is faded but my guess is size Mens Medium.
Some fraying at one pit. Probably an asset to this battle jacket... or as an art punk thing would it be a crit jacket?
Pit to pit: approx. 19.5 - 20"
Neck to hem: approx. 24"
