It’s summer! And that means on Fridays, everyone should be sneaking out of work a little bit early to go on a weekend jaunt or grab a drink on a sunny rooftop. The fashion industry, which works very hard, also knows a thing or two about how to cut loose. In our weekly Summer Friday column, we catch up with industry insiders to find out what they do, where they go, and what they bring with them when they escape the daily grind. Last week we went on vacation with Esquire’s own Wendell Brown. This week we go on vacation designer and mommy Rebecca Minkoff.
