“How’s my photo?” chirps a young woman holding up a Polaroid selfie to her friend. They are huddled in an aisle at a basement consignment shop on Tokyo’s tree-lined avenue Omotesando, surrounded by clothes, furniture and sundry knick-knacks, preparing a vintage handbag for display.

“Cute!” the friend replies. “I think you can sell the bag for much more with that smile pinned on it.”
