Attention, fashionistas: New York is on fake Birkin alert! There’s been a sudden influx of faux Hermes Birkin bags around the city, popping up especially on subways and buses. Our accessory-aware source laughed, “It seems like everyone who wasn’t in Aspen or St. Barts over the holidays must have gone to the same place to get their ‘It’ bags. Even Olivia Palermo (pictured) is sporting one.” The real things sell from about $2,000 up to $65,000.
