See bottom of post for update.
Paige Denim's corduroy jeggings retail for $148 at Shopbop and also come in black.
The color is lighter on these AE cord jeggings, but they'll save you over $100! They also come in a caramel color, which would also be great for fall and you can click on the photo below to purchase.
*Update - 9/28/10* - Gap has another option for the Paige Verdugo Jeggings, and they retail for $59.50 (use code GAPSAVE for 25% off - good thru 9/29/10). I just purchased these and they run about a size small, so whatever your normal Gap size is, go up one! Click on the photo below to purchase - also available in black, red, or indigo.
How do you feel about corduroy jeggings? Do you plan on picking up a pair for fall?
