It feels like a migratory pattern has suddenly reversed: a herd of New Yorkers has landed in Los Angeles this week, trading their downtown swagger for sun-drenched lunches at San Vincente Bungalows and coconut-milk cortados at Erewhon. Of course, I'll be joining them. For me, the co-mingling kicks off on Thursday night with a fête for Laura Brown—the sharp-witted Australian media maven and former InStyle editor-in-chief—and Kristina O’Neill, the effortlessly polished former editor of WSJ. Magazine, celebrating their new book All The Cool Girls Get Fired at Tory Burch in Beverly Hills. I'm anticipating peak bi-coastal glamour: sharp tailoring, sculptural jewelry, and enough lace to remind us summer isn’t completely over—at least in California. On the same night (of course!), Kallmeyer is hosting at The Dresden with, no doubt, guests in the line's enviably-cool minimalism. Think signature tuxedo shirts (now on sale, below, which I snapped up for the occasion), and dresses that drape just right. However, since denim is practically the official uniform of Los Angeles, jeans will be out in full force—but this week they’re getting a sophisticated upgrade for our visiting Manhattan set. I love the pinstriped pair by Zara, above, and these suede-trimmed(!) J.Crew, below. I'll also be dropping by Attersee's trunk show at Sunset Tower to not only take in the refined sensuality of Isabel Wilkinson’s architectural silhouettes but also the crowd of linen-and-gold-wearing devotees who looked like they just got back from summering in Hydra. And because no New York takeover would be complete without a hit of Tribeca edge, I'll be hitting Nili Lotan's spring preview today--and fast-forwarding to Marlien in March, wearing the line's signature slouchy barrel-leg pants, gauzy shirting, and faux fur-trimmed army jackets (below) that whisper cool more than they shout. I'm plotting to show my fellow New Yorkers the good side of the 405 by wearing this boucle 3.1 Phillip Lim knit, this studded Pistola jacket (I'm sporting it as a shirt), this Tibi car coat, this fringed Dries Van Noten, these tasseled Jimmy Choo loafers, or this multi-pocketed Mango. This week will be going by faster than a New York minute!
