Why the Stars Can't Get Enough Prada

From Lindsay and Amanda to Paris and Nicole, Hollywood's hottest stars turned out by the dozens at the Waist Down Skirts Miuccia Prada event in Beverly Hills.

But it was the Prada bag that got fashion's It-girls talking.

"Every girl wants a Prada handbag," Nicky Hilton insisted.

Yes, it's a must-have accessory of the season, and fashion expert Merle Ginsberg gave "Extra" the lowdown on the hot new styles. But they don't come cheap; the Napa Gauffre can run up to $3,000.

"Madonna bought this," Ginsberg showed us. "It's got the gorgeous leather. It's very, very big."

Bigger is better this season when it comes to bags, and skins are in!

"It's all about leather and suede and various antique leathers," Ginsberg explained.

The Cervo, which starts at $2,000, is a favorite of Naomi Watts and Liv Tyler. Keira Knightley on the other hand is a fan of the $1,300 Mui Mui Coffer.

"If you want to buy one bag that lasts you for many years, this would be a great one to have," Merle insisted.
