For the past six years, at 8 a.m. sharp, Andreas Anastasis has walked to Anna Wintour’s Greenwich Village town house, where for about 20 minutes every weekday he maintains upkeep, whether it’s cutting, coloring, spraying, blow-drying or styling, of the most instantly recognizable bob in fashion — maybe the world. A short distance from there, “right across the street from Carrie Bradshaw’s house,” he has spent nearly a decade running his namesake salon, where he now works two days a week. The only magazine in the waiting area is Vogue.
