Cannes is an exhausting marathon of a film festival. It goes for 11 days, and this isn't like Sundance where dress is semi-casual. Oh no, celebrities are expected to be on top of their game, dressed to the nines for Cannes. So it's understandable that after day after day of red carpet wear, some of them eventually slip up.

With the good, you have to take the bad. We just finished our top 5 best dressed list for the first half of Cannes, and now it's time for the worst of the bunch.

We look forward to the Metropolitan Museum Costume Institute Gala every single year! We wait with anticipation to see what kinds of amazing dresses all the beautiful stars are going to wear on one of the biggest nights in fashion. But let's not kid ourselves -- we're also anxious to see whether anyone goes out on a limb and wears something crazy or horrendous. There's a lot of pressure to get it right on a night like tonight, so for those that fall, they fall hard.

Browse through the gallery to see who did not make our best dressed list. And we should clarify that some of the dresses aren't actually that horrible. But the best dressed list was full of so much gorgeousness that anything less than perfect just couldn't make the cut.

InTouch did a reader poll to find out which female celebrity deserves the title of Worst Fashion Offender of the year. Obviously the Olsen twins won. Is anyone really surprised by that?

But, there were a few shockers too. Victoria Beckham was on the list. Personally, I think she dresses well. Her style isn't all that original, but it's certainly not bad enough to be considered offensive!

Anyways, the rundown goes like this: Mary Kate and Ashley Olsen, Courtney Love, Sharon Stone, Victoria Beckham, Tilda Swinton, Lindsay Lohan, Amy Winehouse. Let's discuss.

Courtney Love and Sharon Stone are basically permanent hot messes. All in favor of their placement on the list say, "Ay." AY!!!!

Lindsay Lohan has long since worn out the welcome of leggings as part of fashion. They were cute for about a minute, when properly placed underneath long tunic tops or short dresses -- not as pants.

Amy Winehouse constantly looks dirty and drugged, so I think it's safe to say she probably doesn't even realize what she's wearing half the time. I feel like we can't hold her responsible for the horrible fashion choices she has made.

Tilda Swinton isn't enough of a Hollywood player to be on this list (and I do mean fashion wise, because I realize she's an amazing actress). Sure, her Oscar dress was bad. Really bad. But, aside from that can you actually remember any other outfit she's worn to any other event? I doubt it.

The choice of Victoria Beckham totally confuses me, but I already said that. And, as for the Olsen twins, love 'em or hate 'em, they always keep people in the fashion world talking.

Do you disagree or agree with the women on this list?

Nicole Kidman is one of my favorite pale ladies in all of Hollywood. But, I wish she would own her skin color. Wearing a black dress when your skin is as white as snow can sometimes make one look rather witch-y.

I also wish she would own her pregnancy! Show it off Nicole! Every gossip blog out there knows you've been wanting to have biological children since back before you starting botoxing the life out of your forehead, had red hair and dated pre-couch jumping crazy Tom Cruise. And now Keith Urban's golden sperm has done the trick. You're finally knocked up, so give us what we've all been waiting for -- a glimpse of that little baby bump!

Honestly, there's not that much wrong with this dress. It's kind of an awkward length -- like someone accidentally hemmed it just an inch too short. And it's a little boring. The plain black looks sort of like a prom dress, I mean if it weren't worn with a ridiculous diamond necklace, which is most certainly worth more than my house. But, I can't really put my finger on what I don't like about Nicole's Oscar get-up. I think I just expected more from one of the most elegant women in the business.

Tilda Swinton is a great actress! So I don't get why she always wears totally insane outfits to award shows. She should know how to work the red carpet by now, but for some reason she insists on dressing in the most unflattering clothing that she can get hands on.

This year, Tilda's unflattering outfit of choice is what looks like a giant velvet trash bag. She did get the memo that one shoulder is in, unfortunately, she took it one step further and went with just one sleeve. Her poor left arm must be cold with all the wind and almost rain going on today!

And I'm pretty sure she doesn't realize that she's at the freaking Oscars! I understand the need to look natural. I have no problem with ladies who aren't girly and into wearing tons of making. But you just cannot go completely barefaced to the Oscars. Hilda, you are at the biggest event of the year. A little bit of lip gloss never hurt anyone. And would it have killed you to smile?

PETA has given the crown of worst dressed celebrity of the year to Miss Aretha Franklin. Lauren already talked about how Queen of Soul is notorious for mistreating her ladies, but apparently she's also notorious for mistreating animals via wearing fur. PETA says, "How 'bout some R-E-S-P-E-C-T for animals? Aretha, when you waddled into the Grammys in yet another vulgar fur, you looked as if you were going to perform 'I Am the Walrus' by the Beatles. You might be a queen, but you don't know jack about compassion."

And that's not once, but twice in the past month that they have attacked Aretha for her weight. PETA recently sent her an open letter saying, "Music lovers may think of you as a 'queen,' but to animal lovers, you are a court jester . . . Why not shed the old-fashioned look that adds pounds to your frame and detracts from your beautiful voice?"

Really, was it necessary to bring up Aretha's extra poundage? I think PETA could get their point across without going there.

Coming in as runners up on PETA's annual worst dress online poll are Lindsay Lohan, Eva Longoria, Kylie Minogue, Kate Moss and Marilyn Manson. Respectively, PETA calls Lindsay Lohan "skanky," Kate Moss is a "super tramp" and Eva Longoria is a "streetwalker."

I guess PETA just wanted to remind us why they aren't known for their subtleness. Remember their parody of the Olsen's? They have a whole website called "Meet the Trollsen Twins."

Really, I think it's silly that PETA thinks attacking celebs will stop them from wearing fur. Don't get me wrong, I'm not big on wearing anything that was once cute and furry either. Cruelty to animals is not the answer, but nor is cruelty to celebrities. Make love, not war, PETA!

Of the celebs that will be attending the Oscars this year, there's a few that might want to spend the evening at home, rather than risk perpetrating another serious style foul on the viewing public. The Academy hasn't asked for my opinion (again), but if they did, I'd vote to immediately strike the following invitees from future attendance based on past fashion offenses.

Charlize Theron: what the hell was up with that bow?

Dolly Parton: boobs. (Not that I don't love ya, Dolly.)

Philip Seymour-Hoffman: boobs.

Helena Bonham Carter: her hair at lat year's awards made her look like she lives in a Tim Burton movie.

Jamie Foxx: whoa, is that blue, or did my eyes explode?

Naomi Watts: according to our sister blog, Luxist, "...the dress looked as if she had a bad run in with a lawnmower."

Will any of these style-stunted celebs make a comeback this year? Only time will tell.
