Not too keen on catching the camera-flashes of the paparazzi, Mary Kate Olsen and Ashley Olsen tried to stay incognito as they arrived at LAX airport in Los Angeles last night (March 29).

The always uniquely-styled twins hid away from approaching shutterbugs using sunglasses and a large light blue hat to cover their faces.

Unlike some celebrity clothing designers, Mary-Kate Olsen and Ashley Olsen are involved with each aspect of the apparel-making process.

As the head designers of three separate clothing lines -- The Row, Elizabeth & James and Olsenboye -- the 24-year-old sisters have brought in $1 billion in retail sales through their company, Dualstar. Still, Mary-Kate and Ashley tell Vogue's April issue that buyers weren't always so supportive of their fashion venture.

"We hired a showroom and talked buyers through," Ashley recalls. "People would drill us about fabric, where we'd make it," Mary-Kate adds. "The first season, customers bought it, so the stores came back. And drilled us again."

Still, the twins realized that with no formal design training under their belts, they were in for a tough sell.

"It's a fair question," Ashley notes, "but Dualstar started when we were six. And we had a collection with Walmart at 12, which was the upper tier of the tween market. It was before celebrity designers."

"And we were really designing it," Mary-Kate points out. "It would be jeans, a bit bohemian, or with a little blazer. It was really fashion-forward."

These days, the well-established sisters are finally being recognized for their achievements: they received their first ever CDFA nomination this year. (The twins will face off against Joseph Altuzarra and Prabal Gurung in the Swarovski Award for Womenswear category).

"It's classicist, no-bother stuff. I live in it," raves celebrity fan Lauren Hutton, who once modeled for the The Row's look book. "It's beautifully tailored in a modern way. It just fits, chicly. You know, I look up to them."

With rave reviews and celebrity fans like Carey Mulligan, the former child stars show no signs of slowing down in the near future.

"I want to run a studio," Ashley announces. "I'd probably like to manage other people on their brands. It could be an artist. A young designer. It could be an existing brand."

"The thing about us," Mary-Kate interjects," is we think big. Huge."

Mary-Kate Olsen's got a brand new man!

The 24-year-old has taken her new romance with Seth Campbell public, partying with the "chill" shoe designer at multiple New York City hotspots.

"Their relationship is fairly new," a source tells Us Magazine of the couple, who celebrated a mutual friend's birthday Feb. 16 at NYC's Lavo and made out at a corner table all night. "They've been able to have a few dates on the down low. He's a downtown kind of guy, likes to party every now and then."

The couple also enjoyed a date night out at Mary-Kate's sister Elizabeth's birthday at The Jane.

Adds the source of Campbell: "His company is in the press but he's not, so it works out that way. They're both like each other and are just seeing where things go. Having fun."

Olsen split from artist Nate Lowman in February 2010 after two years of dating.
