Why go scary when you can go sexy?
Here at TV Fanatic, we're celebrating Halloween with 21 of the sexiest costumes worn by some of our favorite TV characters. It turns out cats are a popular choice, but our characters are also dressing up as superheroes, athletes, pop stars, and so much more!
Click through our slideshow and maybe even get some last minute ideas for your own costume. Then hit the comments and let us know your favorites.
Penny - The Big Bang Theory
Remember when the guys convinced Penny to dress up as Wonder Woman for the costume party at the comic book store? She refused to wear the black wig, but as Howard said, no one was looking at her hair.
Lanie - Castle
It's not often we get to see Lanie out of her scrubs, but she doesn't hold anything back with this sexy cat costume. Even Castle can't help but stare!
Barney - How I Met Your Mother
Halloween is a rare occasion when Barney can be found without one of his expensive suits. As great as he looks in his Sunday best, we can't help but stare at his Apollo Creed costume.
Willow - Buffy the Vampire Slayer
Shy, reserved Willow has a hard time showing off some skin for Halloween, so at the last minute she throws on a ghost costume. But, thanks to Ethan's spell, she becomes a literal ghost and her sexy costume is visible again.
Bonnie - The Vampire Diaries
Bonnie is getting into the spirit with this sexy 1920's flapper dress. The red lipstick, pearl necklace, and that georgeous updo help complete the look.
Sarah - Chuck
Sarah shows us just why Princess Leia in the gold bikini is such a popular fantasy. It's safe to say Chuck is on board with this costume choice. He can't take his eyes off of her!
Monica - Friends
Monica got in the Halloween spirit with this sexy, skin tight cat costume. With Phoebe in her red cape, it was Catwoman versus Supergirl at the Friends Halloween party.
