“People want to see actual people on the street. They don’t want to just see a curated outfit on Instagram,” says Double Vanilla, a pseudonymous street-style vlogger who asks strangers to detail their looks.

She convinces well-heeled women (and some men) in New York, Milan, Paris and Miami to slow down and dish about their outfits — IDing everything from their Mango sunglasses to their Chanel shoes, and all the Cartier bangles in between — for short videos she posts to her almost 1mn followers across YouTube, Instagram and TikTok.

She also prices them out. On a recent trip to the French capital, she interviewed a tourist with dark sunglasses and blow-dried hair wearing Tom Ford sunglasses, a Dior handbag and Chanel trainers. Around her neck were three Van Cleef & Arpels bracelets; on her wrist, three gold bangles and a diamond bracelet from the same maison. As she name-checked each label, a price popped up, from $350 for the sunglasses to $78,000 for the bracelets. This walking-around-Paris-with-my-daughter outfit amounted to $152,000.
