Not a manufactured item — a category. On the Shelf, a Ghost Tank is any sleeveless top that's been stripped, cut, bleached, painted, and re-stitched until its original identity is gone. The one in your hand might have started as a Meridian Transit Authority uniform, a Tokusen Industries promo shirt, or a kids' athletic set. Now it's been cut at the shoulders, the neckline widened with a blade, and stenciled with a crow skull or a glitch-art pattern in white house pigment. The hem is raw or knotted. Maybe a strip of reflective salvage tape runs diagonal across the back.

They sell in clusters at Shelf market stalls — three for Φ12, or individually from someone who takes their customization seriously enough to charge Φ18 for a specific piece. No two are identical. Wearing one is a statement that you came from somewhere specific and didn't bother to hide it.
