There is literally no stopping the Kardashian sisters: On the heels of enough product launches to make your head spin, Kim, Kourtney and Khloe inked a deal with QVC to design a collection of curve-enhancing clothing called K-Dash (which Kourtney and Kim are modeling, at left). The line will debut live on QVC's pop-up shop in Rockefeller Center on September 10th at 9pm EST and a runway show will follow the next day. Expect contemporary sportswear and accessories in a perfect mix of the their three distinct styles: Kim (trendy), Kourtney (vintage), Khloe (classic). "If one of us doesn't like it, it's gone," Kourtney told WWD of the sisters' design philosophy. "We all have to love everything." So how exactly will the line complement your curves? All of the denim, cotton, polyester and ponte knit pieces are stretchy—they'll hug your figure instead of hide it. With prices starting at $20 (for a faux-leather wrap belt) and going up to only $239 (for a pebble leather handbag), we'll be snapping up K-Dash items just in time for fall. See Kim and Kourtney modeling more of the collection after the jump!
