Classy

Last night was a good night — we had the pleasure of meeting the fabulous author of Classy: Exceptional Advice For the Extremely Modern Lady, Derek Blasberg at an event hosted by model Maggie Rizer and Gilt Group. He's charming, handsome, not to mention super stylin'. Oh, and extremely funny. Sticking with the book's theme — turning trashy into classy — he divulged his top five fashion no-nos. "The good news is that there are classy girls in the world," Derek said. His tips for staying classy? "Buy the book, don't drink as much, never drink and drive, and use common sense." Read on for more witty recos.

In celebration of Derek Blasberg's first book, friends Lauren Santo Domingo (dressed in Vionnet), Chloe Sevigny (in Proenza Schouler), and Dasha Zhukova (in Prabal Gurung) feted the man-about-town to support his newly-released etiquette guide, "Classy: Exceptional Advice for the Extremely Modern Lady".

Guests including Francisco Costa, Julia Restoin-Roitfeld, Terry Richardson, Chris Benz, Birdie Bell, Tamara Mellon, Vladimir Restoin-Roitfeld, and Giovanna Battaglia sported illustrated "I'm a tramp" or "I'm a lady" buttons while Blasberg signed books in Barneys New York. Post event, Santo Domingo hosted an intimate dinner party in her apartment with Blasberg's parents (who flew in from St. Louis for the occasion) in attendance.

>> Lauren Santo Domingo, along with Chloe Sevigny and Dasha Zhukova, hosted the launch party for Derek Blasberg's new book, Classy, at Barneys in New York last night — with the likes of Zac Posen, Jessica Stam, Jack McCollough, Terry Richardson, and Lazaro Hernandez — before bringing the scene back to her house for a celebratory private dinner. But before Classy, there was Sassy. A number of pictures of Santo Domingo in the '90s hit the web recently, and today, more popped up of her modeling in the March 1993 issue of Sassy.
