Two partiers pose for a picture at Charley's Los Gatos on Oct. 25.

It’s not quite Halloween, but that didn’t stop the revelers from showing up Oct. 25 in their best—and skimpiest—costumes for a night of drinks, dancing and judgment. No… not the “Can you believe what she’s wearing!?” type of judgement. Party-goers were competing for the “Sexiest Costume” prize, and at $500, the competition was fierce.

Check out the slide show below to see some of the naughtiest, and innovative, costumes at the party. Photos by Alex Stover.
