You are such a hipster. You have the Seven Jeans. The Frankie B.’s. You even went to town with a pair of coveted Marc Vachon cords. But — love fashion! — there’s already another must-have. Enter alice + olivia, the new It Girl pants by Stacey Bendet Wiener and Becky Winn. The stylin’ designers named the line after their mothers. (Insert nostalgic, “Oh, how sweet!” cooing sounds.) Sweet? Heck yeah. The low-waisted slacks are made of French, Italian, and Belgian fabrics, lined with patterned silks, and have antique buttons. The signature look? A thick stripe in two colors. And these are no plebeian trousers. At alice + olivia’s premiere fashion show, artists such as Peter Beard, Lulu deKwiatkowski, and Molly McNeely each painted a pair that were auctioned off at Sotheby’s for charity. How’s that for being a walking piece of art? alice + olivia are available at Fred Segal Flair, 500 Broadway, Santa Monica (310-451-7139). For more info, visit their Website.
