Sienna Miller is fashion impaired.

Weasely McWeaselson aka Sienna Miller showed up at a festival a few days ago looking like an instructional example of how not to put clothes together.

For someone whose fame was almost totally the result of being declared a 'fashion icon' it is pretty unacceptable to go out looking like a learning-challenged regional morris dancer.

An evening of celebrity fashion.

All the A-listers turned out for the Metropolitan Museum of Modern Art Costume Institute Gala earlier this week, and of course all anyone cared about was what they were wearing. So without further ado lets get to it, here is a rundown of the celeb fashion in order of best to worst as judged by me:

Best dressed of the night has to go to Kate Bosworth, she just looks incredible, I really think she is one of the most beautiful actresses out there at the moment.





Jennifer Garner, wow, she always looks great:





Call me crazy but I think Mary Kate Olsen looks realy great, much much better than she has in the past, bit of an ostrich dress though:





Eva Mendes looked hot:





Gisele looked beautiful, not sure about the dress but its on Gisele so it gets my vote:





Jennifer Connelly looked good too:





Ellen Pompeo, not so sure about the dress, but she looks beautiful:





Cameron Diaz, at first I hated this but the clashing colours are actually growing on me, and she can pull it off:





Mischa Barton looked okay, nothing amazing:





Not just an evening for the ladies to dress up, Josh Hartnett looked quite dapper:





While Channing Tatum got it wrong and looked like a waxwork:





Lindsay Lohan, meh...





Ashley Olsen looked like she had just thrown her dress on after she had been shopping at Target:





Kate Moss, she just looks haggard, thats what drugs do kids:





Christina Ricci and Chris Evans, she looks a little creepy and he is just boring:





Parker Posey, as much as I love her just didn't quite get it:





Jennifer Lopez landed from space for the event, quite appropriate since she has allegedly converted to Scientology in secret:





Rose McGowan looked, well, elderly:





Jessica Simpson continued on the path of trying to look like a female impersonator:





Alicia Keys just looked way older, and more pregnant, than she is:





Liv Tyler, no, just no, the colours look terrible, she looks like a cross between Ronald Mcdonald and an 89 year old woman:





And the accolade of ultimate worst dressed goes to, surprise surprise, Kirsten Dunst, who looked like a flapper that had been dead since the 1920s and was dug up for the event. She was accompanied by Johnny Borrel who may well be the strangest looking man on earth, and cowboy boots with a tux? um...nooo:

Kirsten Dunst is confusing.

As much as I dislike Kirsten Dunst, I have to admit that she looks pretty nice at the Italian premiere for Spiderman 3 in Rome.





but she hasn't been so successful at the other Spiderman 3 premieres across the globe. In London she went with goth-slash-binliner chic.







In Paris she looked like a Christmas present.





Doesn't she look thrilled to be there?



In Madrid she just showed up in an old jumper.







AND THEN, my personal fave, the premiere in Stockholm. Dear sweet god.







I kept the pictures small to avoid adverse reactions. If that isn't grounds to sack the stylist I don't know what is...
