The first week of the Cannes Film Festival was, as always, a couture fashion show of international proportions featuring stunning creations by Giorgio Armani, Ferragamo, Versace, Chanel, Max Azria and Christian Lacroix worn by stars such as Cate Blanchett, Angelina Jolie, Julianne Moore and Natalie Portman.

The finest rocks from Bulgari, Van Cleef & Arpels and Chopard decorated the ears, necks, wrists and fingers of both the filthy rich partygoers and the film famous.That's not even counting all the Christian Louboutins and the Jimmy Choo stilettos teetering up those Palais steps.

And it's not over yet. There will be another fashion free-for-all this week, with Sharon Stone and Madonna due in town for the star- studded AmFAR Cinema Against AIDS fundraiser.

But let's be honest. Not everyone who shows up in Cannes' global media spotlight has (A) a good reason to be there or (B) the skill (or stylist) to dress appropriately for the big occasion(s).

In fact, it's hard to fathom why both "Desperate Housewives" TV star Eva Longoria and desperate former talk show host Star Jones were at Cannes, wearing all manner of glam gear and fashion finery to several premieres and parties.

Let's take a closer look at the good, the bad and the simply inexplicable highs and lows of the fest's annual fashion show.
