Every year, come October, there’s a mad scramble to come up with that GREAT Halloween costume idea. The best costumes fall in to 1 of these categories: 1) Hilarious 2) Topical/Relevant 3) Sexy 4) Clever or 5) Unique.

If you’re a person that prides themselves on really good Halloween costumes — check out our slideshow above for 25 costume ideas that may just earn you the “Best Dressed” prize at the party this year. Go get ’em!
