What’s Nicky Hilton up to these days, you ask?

“I just finished my first book, which will be coming out in the fall to coincide with New York Fashion Week,” she told Buzz at the Wildfox fashion show at Pier 59. “It’s a style handbook, all about my tips and tricks and tales I’ve learned along the way.”

What kinds of sartorial wisdom can readers expect?

“It’ll be for everyone, not one particular type of girl. It explains how to navigate a store, clean your closet, what to keep, store, buy, how to dress for each season. I know a lot about clothes!”

Accompanying the quieter Hilton was brother Barron, sporting still-fresh scars from a brawl with a pal of Lindsay Lohan’s at Art Basel Miami.

“A buddy of mine’s doing a show with En Noir, they’re doing a collaboration with [DJ] Steve Angello,” the boisterous brother said. “This is actually my first fashion week. I’ve never been! I’m just tagging along.”
