BARRETT HOPS THE POND: It’s only taken 10 years, but designer Neil Barrett will make his first U.S. public appearance this weekend, at Bergdorf Goodman Men on Saturday afternoon. “I’ve only done four of these events in my life, but I need to dedicate time to the American market. Bergdorf Goodman is my best U.S. account. They’ve done incredible increases, season by season,” said Barrett, who is known for modern tailoring with punk influence. In addition to suits and vests, Barrett’s leathers do well at the store. While he’s in town, he plans to see a Katy Perry show. They’ve been friends since before she got famous for kissing a girl. Then he’ll head to Los Angeles on Wednesday to do a few celebrity fittings and spend his birthday weekend in the sun.
