It's October and you know what that means? HALLOWEEN! And that also means it's almost time for the annual SM Entertainment Halloween Party. Each year, SM artists amuse fans with their creative and unique costumes - making us go 'Woah' or 'LOL' in amazement. But out of all, which idols really stole the spotlight with the BEST costumes? Slide next to see the SM stars who have won Halloween with their epic looks!

Catwoman and Minnie Mouse can be considered pretty typical for Halloween but these cute, sexy looks were beyond the norm when pulled off by Yuri!

Chen as a yogurt ahjumma was and will continue to be the funniest in SM Halloween Party history. I mean, just look at those red lips.

No, not because Changmin's topless but because he looks like he just jumped out of the cartoon! The accessories, outfit, (his hot bod) are on point.

Another idol who looks like he was just ripped right out of the cartoon. Minho is a handsome replica of Detective Conan.

Probably the prettiest Anna of all.

Who knew Sadness could be such cuteness? This 'Inside Out' cosplay by Sooyoung was brilliant!

Key, a.k.a the master of costumes. Every year Key goes viral for his unique ideas and perfect portrayal of the character. From Scissorhands to Ronald McDonald... I'm lovin it!
