This is it. This is going to be the Halloween when you finally go all out and wow your co-workers, friends and fellow partygoers with a truly magnificent costume. As you head into the final week of Halloween prep, we thought we would highlight some of the best celebrity costumes from Halloweens past, for a final burst of inspiration.

Sexy, adorable, weird - they're all here. Let us know which one is your favorite. And if we missed one, sound off in the comments.

1. Snoop Dogg as...a pug

Sometimes you choose the pug life. Other times, the pug life chooses you. In either case, all you need are some dance moves to bring your pug game to another level.

2. Katy Perry as...a Hot Cheeto

The Cheeto bag-purse is a nice touch, don't you think?

3. Sandra Bullock and Melissa McCarthy as...grizzled fishermen

It's nice to see these wizened old sea salts take a break from the angry seas and enjoy some trick-or-treating.

4. Neil Patrick Harris as...Obi-Wan Kenobi

NPH and his adorable family recreated the original Star Wars trilogy. The Force is certainly with them.

5. Rihanna as...a Ninja Turtle

Y'know, this is a much better look than whatever is going on with the Turtles in the latest series of reboots.

6. Kim Kardashian as...a skeleton

Socialite, businesswoman and internet-breaker Kim Kardashian went with a fresh spin on an old classic. And speaking of Kardashians...

7. Ellen Degeneres as...'Karla' Kardashian

Last year, Ellen created a long-lost Kardashian sister for the Halloween edition of her talk show.

8. Kevin Hart as...Martin Lawrence

Comedic powerhouse Kevin Hart paid tribute one of his influences, standup comic and actor Martin Lawrence.

9. Whoopi Goldberg as...Cruella de Vil

Hide your puppies! 'The View' co-host and cannabis entrepreneur is here, decked out like the legendary villain from '101 Dalmatians'. 

10. Emily Ratajkowski as...Marge Simpson

This costume is so good it more than makes up for the trail of yellow paint she must have left on the furniture.

11. Heidi Klum as...95-year-old Heidi Klum

No list is complete without a nod to the reigning Queen of Halloween. Whether dressed as an older version of herself, Jessica Rabbit or, uh, a skinless corpse, Klum goes all out with her Halloween attire.
