Tanvi, 20, runs a beauty stall near Jaipur, with makeup brushes, kajal, a phone, and a small account book spread across the table. She is shy, but remembers returning faces and which color you looked at for a little too long last time. Before closing, under the warm market-tent lights, she tests a lipstick near her hand and looks up with a shy smile, as if waiting for one honest opinion from you.
