# In Use | No. 547, Unisex T-Shirt

Intricate cross-hatch ink details form the brushed metal hardware of a sliding public door lock. The mechanical grit of the scratched plates and handle knob contrasts sharply against the bold, flat red indicator square. Inside the stark red block, crisp white lettering spells out the universal signal of occupancy alongside Japanese characters, anchored by a bright red dot next to the bolt. Printed on a short sleeve t-shirt, the high-contrast graphic creates a striking focal point.  
  
A simple everyday mechanism becomes a study in personal boundaries and the quiet necessity of closed doors. It is a universal artifact of claiming space, even just for a moment.
