Kourt, Khloe and I had so much fun looking through all of your entries in our 'Costuming Up with the Kardashians' competition! We didn't expect to get so many pics of adorable kids and pets too!!! It was really tough choosing our top three costumes, but we whittled it down in the end and all agreed on our favorite... Celebuzz posted a gallery of our favorite 40 in a costume countdown, so click through to find out who our grand prize winner was!

Thanks to everyone who entered!

You all know my sisters are huge fans of dressing up. Whether it's for a red carpet event, a photoshoot or dinner with family and friends we love to get all glammed up, so naturally Halloween is one of our favorite holidays! This year we have teamed up with Celebuzz to do a super fun Halloween costume contest, Costuming Up with the Kardashians.

All you have to do is upload your sexiest, most unique costume as a comment on the contest page and right after Halloween, Kourtney, Khloe and I will choose three winners who will receive some awesome prizes!

Head over to the contest page now to enter!
