A lot of old favorites are making a comeback this season – slightly modified of course, to fit this generation’s fashionistas. Below are some of summer ‘09’s hottest jeans trends as seen on your favorite celebs.

Cuffed Khakis

Celebs like Jennifer Aniston, Rhianna, and Kristen Bell breathed new life into the classic chino and made it look cool, with rolled up hems, and a more casual, slouchier fit.

Cropped Harem Pants

Another resurrected bottom-wear made it into this season’s must have bottom wear. Fergie, Diane Kruger, and Olivia Palermo were all spotted wearing harem pants that were cut off at the knee.

Denim Leggings

Denim just got comfier, as it suddenly became the material of choice -the stretchy type – for sexy leggings. Stars like Beyonce were seen sporting her skintight pair which were offset perfectly by a long, white Balmain blazer.

Pale, Distessed Jeans

Stars like Katie Holmes are fans of J Brand’s "Zombie" jeans, which merged two trends in one: tie-dye in light shades of gray and/or blue, and rips and tears at the knees. It’s young, edgy, summer.

Blue-black jeans

On the other end of the spectrum, blue-black jeans are making the rounds as well. Slim type, ink-washed jeans can sub for your black pants, like what Cameron Diaz did with her pair, balancing her slim jeans with a loose, colorful top.

Tie-dye Jeans

Denim designers seem to be getting inspiration from decades past. Check out Fergie’s tie-dye indigo jeans with bold white splotches. People.com described this trend as a "60s hippie meets an 80s punk rocker." Follow Fergie’s cue and pair your tie-dye jeans with a tailored blazer.

Motocross Jeans

If you prefer a more subdued style, but still want to maintain a bit of edge, then follow Kylie Minogue’s lead and go for motocross styled jeans, complete with stitched details around the knee.
