this is halloween, everybody make a scene

For some last minute inspiration, here are some of my favorite photos of costumes past:

Mary-Kate Olsen is a moon goddess

Zooey Deschanel and Joseph Gordon-Levitt channel their (500) Days of Summer relationship and do Sid and Nancy up right

Anne Hathaway as Cleopatra

Audrina Patridge of The Hills pretends to be 'Like a Virgin' in her Madonna getup

Meredith Viera and Al Roker channel The Munsters for a Today Show segment

Charlize Theron - all she needs is a glamorous gown and a Venetian mask to have an elegant costume

John Legend and his date play Cowboys and Indians

Not quite sure what these costumes are - but they do look fabulous

The Beatle boys and girls at a costume party celebrating the release of the Magical Mystery Tour film

Strangely enough - same Beatle era, different costume party.

The Rolling Stones dress as circus characters for their Rock and Roll Circus special

Agyness Deyn and Alexa Chung as Wayne and Garth (party time, excellent!)

Always a Halloween standard: a cute cat

No one can rock a sequin suit and top hat quite like 'Nell
