"I started spitting out ideas and she started drawing," Cardigans frontwoman Nina Persson said of her new capsule collection with designer Ann Ringstrand, which debuted at the ACE Hotel's Liberty Hall last night. Ringstrand, of Swedish label HOPE, said she approached Persson to do the line after she saw the singer and her band A Camp wearing HOPE on stage, and the two laid the foundation for the line over a bit of brainstorming in a hotel room. The collection, which favors soft peaches and grays, has a touch of 30s style (coats with wide fur collars, drop wasted billowy dresses) and whimsy (the "Guilty" skirt is made of mesh). "These are the clothes I miss," Persson said, that I used to dream about finding -- the perfect coat with the right buttons, the right collar, all of the details I could never find all in one piece of clothing." Ringstrand said the looks included in the line were almost all born from Persson's ideas, and that she only occasionally took the reigns to add practicality to a few pieces. "Sometimes I had to say, 'that's not going to work," she laughed. Persson and Ringstrand, however, appear to have formed a nice creative partnership: Attendees - who included Sarah Sophie Flicker and James Iha -- all made their way over to touch the coats and dresses before a pregnant Persson and A Camp performed live. Persson and Ringstrand's capsule collection will be available at Project No. 8 and La Garçonne.
