Designer-denim fiends should head over to Net-A-Porter, where the first shipment of Victoria Beckham Denim just hit the e-retailer's virtual shelves.

For fall, the world's most famous soccer mom is continuing the themes from her Spring 2010 collection of clean lines, sexy panels, and zipper detailing.

The first two super-skinny styles available on the site include a $315 mid-rise light blue pair with angular gray cord panels on the lower leg, and a $450 low-rise black pair with gold zippers cutting across the hips, thighs, and ankles.

We also got a glimpse of two other soon-to-be-released pairs we think are even better than the first shipment. One is a black waxed denim motorcycle pant with rumpled knees, zip-up hems, and paneling. Another is a narrow, bleached-out pair that is practically white and spotted with man-made rips on the thighs and knees.

As more pieces roll out, expect to see luxe embellishments like antique mirrors, beaten metal, and Lurex and lace inserts combined with the denim, in addition to dip-dyed hems and ruching.

Beckham is also expanding her jersey capsule collection to include cropped wool cardigans and vests and leather pieces such as the iconic bomber, as well as second-skin Napa leather leggings, all made in Italy.
