Former Girlfriend Now A Star

Wherever she goes, the paparazzi catch every moment, every turn, and every curve. It's been like this since Shoshanna Lonstein captured the heart of America's favorite television star when she was just a high school senior.

Her romance with Jerry Seinfeld is long over now, but now she's making headlines of a different fashion, reports CBS News 48 Hours Correspondent Troy Roberts.

"I see so many women wearing things that don't fit right," she says. She's designing clothes for shapely women like herself.

At 23, she's the talk of the fashion industry. In less than a year, her clothing line has succeeded beyond her wildest expectations. She is already generating sales in the $1 million neighborhood. "That's probably a conservative figure," Lonstein says.

After graduating from UCLA with degrees in history and art history, Shoshanna began a career in a business she knew embarrassingly little about. After a year-long apprenticeship, she had designed a collection of sample dresses.

"I basically would show them to people and go, 'so, you gonna give me a company, or how does this work'?" she remembers. No one gave her a company, so she started one of her own. It's called, of course, Shoshanna.

Her father, Zach, a successful computer entrepreneur, gave her the initial backing and still advises her at weekly strategy sessions around the kitchen table. The original intent was for it to be almost a cottage industry, one created by a young woman who still lives at home with her parents. The notion of a small business diminished with her first major sale: to Bloomingdale's.

The product is now being sold in 180 stores across the country, and it's moving so fast that Shoshanna can barely keep up with the demand. While Shoshanna is a long way from enjoying the name recognition of Madison Avenue moguls Ralph Lauren or Giorgio Armani, her business is expanding at a speed unheard of for new designers.

"I really feel successful right now," she says. "I mean, I don't know where this will take me, but it doesn't need to take me much further. I'm very happy where I am."
