Thursday, April 10th

Are you opening a store? Then you need a busload of dames! Christian Lacroix opens his 57th Street boutique with a haul of pulchritudinous peaches such as Kim Raver of Lipstick Jungle—the reason we’re not (that) scared of 40 anymore—Cristina Greeven Cuomo, Vanity Fair’s Amy Fine Collins, Allison Sarofim ( best known for Halloween parties), the recently emancipated Blaine Trump, stylist Rachel Zoe and designer Diane Von Furstenberg. Make our peach-papaya cosmo-tini a double, please! And then, ladies, it’s time to do good for Fido (may want to leave the fur behind for this one): Animal lovers dress in orange and congregate in Union Square to meet the stars of Animal Precinct and adopt eligible canines. Woof! Finally, The Observer’s own sartorial genius Simon Doonan spiffs up Barnes & Noble with a reading from Eccentric Glamour, his latest fashionable tome. “Simon Doonan promises to machine gun the audience with vital style tips,” e-mailed the man himself. “He will also share some of the low-points of his career, including his tragic forays into the cut-throat world of celeb impersonation. His specialty was QE2.”
