Former model Molly Sims will soon pull an Elle Macpherson and design her own lingerie line. “It’s something I’ve always wanted to do,” Sims tells PEOPLE on Wednesday night at the LA launch party for Domino: The Book of Decorating. And now she finally has the means to do it on a mass level, thanks to financial backing from a company called Concepts. The Las Vegas star insists she prefers substance to flash, so bet on comfy, practical designs over tassels and frill. One print that definitely won’t make the cut: leopard. “I want it be what you wear, not what you wish you could wear,” Sims explains of the collection, which will hopefully be released for Spring 2010. “It’s what you wear every day, just a little more beautiful. It’s going to be feminine. It’s like undone-done, so it’s like a reveal-conceal,” she sums up at the poolside bash, held at the Beverly Hills home of Top Design judge Kelly Wearstler, who kept guests like Sims, Gwen Stefani and Gavin Rossdale outside. “It’s so not done, and I’m such a freak,” the perfectionist designer says of her home. “But there will be another party,” the Domino cover girl promised. May we suggest a possible launch party for Molly’s line? — Jenny Sundel
