Paris in Wonderland: Paris Hilton donned two revealing outfits for a weekend of Halloween partying

Wearing a strapless corseted minidress decorated with anchors, topped off by a sailors hat, Paris showed plenty of her perma-tanned leg.

But it was her second outfit in which she upped the raunch factor as she adopted a demented Alice in Wonderland theme with a white PVC minidress, with layered petticoats, suspenders and stockings.

And the final touch of drama, a pair of bizarre contact lenses.

Paris was letting her hair down after working on a film in Toronto all week and after getting in a row with an adult movie shop which was promoting her infamous home-made sex tape 'One Night in Paris'.

Petulant Paris demanded that the promotional posters were torn down, and threatened to sue the store for all they had. Apparently while wearing another costume - this time a skeleton and mask outfit.

But the ex-jailbird wasn't the only celebrity out on the Halloween prowl. Desperate Housewife Teri Hatcher, looked a right fright dressed as the Queen of Hearts at the Dream Halloween charity bash.

Wearing a face full of clown-like make up, and a tightly corseted ball dress, Hatcher's outfit was a red carpet nightmare. But on this occasion it was fitting.

But the weekend's hot ticket party was actress Kate Hudson's Hollywood bash. Attended by on/off boyfriend Dax Shepard, Mary-Kate Olsen and father Kurt Russell.

Aerosmith singer Steven Tyler looked as if he was wearing his stage-make-up as he joined the stars out on the town for the big party weekend.
