After flying solo at the Diesel party, Lindsay Lohan was back with Samantha Ronson again to catch Madonna's Sticky and Sweet tour at MSG last night. LL has been busy in NYC, and according to her MySpace blog, she'll be launching her leggings line later today. She said, "I'm thrilled to announce that my new fashion collection, 6126 is finally ready for launch!! I love to wear leggings, so it should come as no surprise that my first venture into the world of fashion design is with leggings!" The event will take place at Henri Bendel with a percentage of proceeds going toward ovarian cancer research. We've already gotten a look at some of her creations, but we're interested to see the holiday line, especially those cozy-sounding cashmere leggings.
