Shoshanna Lonstein Gruss built a career as a fashion designer and entrepreneur after her relationship with Jerry Seinfeld drew public attention. She was 17 when the relationship began, according to a 2000 Los Angeles Times profile; Seinfeld was then in his late 30s. Today, she is identified by her clothing brand as its founder and creative director.
What happened after her relationship with Jerry Seinfeld?

She did not offer a public account of the relationship in that profile. The Los Angeles Times reported that she would not discuss Seinfeld and had made the interview conditional on not being asked about her personal life. That boundary matters: there is no basis here for assigning her feelings or a private explanation for the relationship.
How did Shoshanna become a fashion brand?
From UCLA to a first collection
According to the company’s official biography, Lonstein studied history and art history at UCLA and later worked at a New York lingerie factory, learning about design, fabric sourcing and garment construction. The first Shoshanna dress collection debuted in stores in November 1998.

#1 Best Overall
In the 2000 Los Angeles Times profile, Lonstein described a practical reason for starting the line: she had clothes custom-made because ready-to-wear options did not fit as she wanted. She said she saw a gap for women whose sizes fell between those available in stores. That was her explanation for the business idea, rather than an independently measured account of the market.
Swimwear and later collections
The company’s biography says Shoshanna added swimwear in spring 2001, with tops and bottoms sold separately and sizing inspired by lingerie. It also describes later extensions into children’s swimwear and eveningwear. These milestones and descriptions come from the brand itself.
What does Shoshanna Lonstein Gruss do now?
Shoshanna’s current biography identifies Lonstein Gruss as the brand’s founder and creative director. The company describes its collection as including dresses and swimwear. That is the clearest documented answer to what she does today: she is associated with the fashion business she founded, rather than defined only by her past relationship.
