Lindsay Lohan recently began designing the new collection of leggings for her brand, 6126. "We just want to do something really cool this time, like a great photographer to shoot it and just something really fun," Lohan told us at the Matthew Williamson boutique opening last night. Her design inspiration, she says, is Karl Lagerfeld: "Everything Chanel." She admires Wolford tights, which she says are the best. And like the Kaiser, Lohan refuses to scrimp on quality. "I'm not going to compromise my line and what I do for girls to wear on their legs for what the price is and what's going on in the economy," LiLo says. "I still want girls to feel good and look good." And to better serve her customers, Lohan intends to expand her product line."There's only so much you can do with leggings," she admits. "So we'll expand soon."
