Mary-Kate & Ashley Olsen

For six seasons, Ashley and Mary-Kate’s high-end women’s line The Row has been flying off store shelves. Stars like Katie Holmes, Heidi Klum, Gwyneth Paltrow and more have all been spotted wearing looks from the line. Now, the designing duo is expanding their line into menswear with a 35 piece Fall ‘09 collection. Like The Row’s women’s collection, the men’s line will combine classic tailoring with comfortable American sportswear. From cashmere overcoats and jackets to chunky knits and soft T-shirts, men can now incorporate the Olsen’s coveted designs into their own wardrobes. The collection will range in price from $250 for a t-shirt to $3,200 for an overcoat, and store availability is still to be determined. We think it’s only a matter of time before we start seeing some of Hollywood’s hottest guys in The Row as well.

A celebrity nearly from birth, Ashley Olsen is the last person you’d expect to get stage jitters. But at last night’s Fashion Group International’s 25th annual Night of Stars in N.Y.C., where she was slated to give a speech honoring Calvin Klein’s creative director Francisco Costa, the star admitted to PEOPLE, “I’m nervous,” adding wryly, “There’s a story there.” The actress, clad in a Calvin Klein column dress, arrived on Costa’s arm, and got a head-start praising her friend, saying, “When I first moved to New York, he’s the guy that really captured my eye. I followed [his work].” For his part, Costa was no less effusive about Olsen’s designs for her labels The Row and Elizabeth & James — especially when it came to the perfect fit of The Row’s pants. “They are actually great,” he said. “In fact, I was with Lauren Hutton. And I said, ‘You look so great!’ And she said, ‘It’s The Row.’ I was just so jealous.” So what does he think accounts for Olsen’s style success? “She really understands herself,” he says. “It’s mostly just what she feels comfortable wearing. It’s her eye.” Olsen sees the same in Costa. “I think it is all in the details for him,” she says. “It’s all in his head. Even if it looks like just a simple garment, you can go up to it and see the details that not many people would consider while fitting a garment.” – Jeffrey Slonim

Not content with their already booming fashion empire, Mary-Kate and Ashley Olsen are adding to their already successful Elizabeth and James Line — with jewelry, reports Women’s Wear Daily. The designing duo have teamed with famed jewelry designer, Robert Lee Morris, for their newest adventure in fashion. After seeing Morris be honored with a Lifetime Achievement Awards at last year’s CFDA Fashion Awards, the twins set their hears on working with the industry legend, who has created pieces for everyone from Calvin Klein and Donna Karan to Karl Lagerfeld in his forty year-plus career. The Olsens and Morris have created 80-plus styles for the jewelry line, including cuffs, earrings, necklaces and rings made from silver and antiqued brass. Motifs snakes, beetles, crosses and daggers. Ashley Olsen tells Women’s Wear Daily, “The symbols are attachable and you can take the jewelry and make it your own. There are solid silver and gold pieces to wear forever and comfort pieces that you’ll put on and wear everywhere.” Pieces will range from $65 to $700 and will hit Intermix stores nationwide in September.
