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!

Reggie and I hit up some parties on Halloween night and look what we found, a Reggie and Kim! I love it!! A bunch of you guys Twitpic'd your costumes so I wanted to share them with you all! Which couple do you think had the best Reggie and Kim look?

After Kendall's 14th birthday costume party, I flew to New Orleans to spend Halloween there. Reggie's original costume didn't come in the mail in time, so we will save it for next year... we went to a Halloween store and got him a crazy mask! It was so funny! I copied Khloe and I was Catwoman! She was Catwoman back home in LA.

 

It was Kendall's 14th birthday on Friday night! Kendall was the queen bee and I dressed in my second Disney outfit of the night, Snow White! 

This Halloween was so much fun!! I decided to go as Princess Jasmine, since I've been wanting to go as her for years and found the perfect costume! I went all out with my Disney theme this year and also got a Snow White outfit that I wore to Kendall's birthday! I'm going to post those pics today too! You'll have to let me know which outfit you like the best!

Happy Halloween everyone!

I was looking around Khloe's blog and I saw this pic of us together on Halloween when we were kids. I'm a little 1920s flapper... and how similar is my costume to the one I wore last year!? Hahaha! I just revamped it two decades later! There's nothing wrong with reusing a look or a costume idea and just changing it up! Khloe has been a tiger/leopard at least twice now, hahaha!

What are you all doing tonight!?

As contributing beauty editor for OK! Magazine, this week I did a piece for OK! Beauty on how to create the Twilight inspired look for a sinister vampire Halloween costume. I never really do dark lips anymore, but they are essential for a vampire look. I guess it's like a Twilight vampire, gone goth for the day! Hahaha. Troy taught me all the tips to create this look!

Check out all the press clips from this week!

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!

This Halloween was amazing!!!! Reggie being that he is on his bye week, came home to L.A. for the weekend, and we dressed up as a 1920's mobster and a flapper girl!

We went all out! We rented a 1962 old white Rolls Royce, and we felt just like we were stepping out of a Dick Tracy movie! He had the funniest mask too! 

We first went to my mom's house, who has a Halloween party every year! Then we headed to STK restaurant where Jonathan, Simon were throwing a party!

Khloe, Reggie and I ran into Frankie and Brody who were the old president robbers from Point Break! Caroline and Alexander were Sonny and Cher and Khloe was a sexy cop!

After STK, Reggie and I went to my friend Ashley's house and met up with a bunch of my old elementary school friends!

The night was better than expected!

How was your Halloween? What did you guys do?

This Big Bird pic was taken the day before Halloween and a friend of my dad's came over. My dad wanted to see if we were scared or not! We weren't!

If you flip through these pictures you will see more of me and Kourt during Halloween through the years.

Notice the pic where Kourt and I are dressed up as fifties girls—my mom made us those costumes! We wore those to school! Kourt and I wanted to be twins!

The last pic Kourt and I had nothing to do so we took Kendall and Kylie trick-or-treating and dressed up as a cat and mouse! I just wore a gray Juicy sweatsuit and painted my face with whiskers and a little pink nose and Kourt took a kitty costume from Smooch! She kind of looked like a leopard but she was a kitty cat!

I hope you all had a great Halloween!

I decided to be Wonder Woman after all! I really think she is sexy and powerful and we should all feel like Wonder Woman every day! I went to Trashy Lingerie, which is the craziest sexy costume store in the world! They had everything from the boots to all the accessories and corset! It was perfect!

That's right, last night I threw a Halloween party at the Hotel Sofitel in Los Angeles at the Rose Bar inside! All of my Dancing With The Stars friends came out to support! Everyone from Lance Bass, Karina and Max, Jeff Ross, Warren Sapp (his costume was priceless, his Paso Doble outfit), Kym Johnson, Derek Hough, and Cheryl (who got ready with me at my place before the party!)!

My mom and Lara Spencer came together and how amazing were Brittny and her mom Lisa's vampire outfits!? Lisa did all the makeup herself!

Kourtney and Khloe are in Mexico and sooo sad they couldn't make it! The Dash Dolls, and Smooch Dolls all came as Alice in Wonderland-themed sexpots! I love you Lily, Sydney and Roya!

Troy Jensen did my hair and makeup and we took some fabulous pictures! He dressed up as Clark Kent!!!!

My Web producer Meriah Doty also showed up!

It was a great time. Happy Halloween, everyone!!!!

You may be surprised to find out that this picture actually wasn't taken on Halloween, but it may as well have been!

My friends Sarah, Amanada, Amber, Simone and I were the Spice Girls!!! I was Posh!

I honestly was so obsessed with the Spice Girls in high school! How cute are our costumes!?

I'm still getting together a few Halloween costumes because I'm going to a few parties and want to have a different costume for the different nights!

Have you zeroed in on your costume? What are you going as?

My mom goes all out when it comes to holidays!!!! Halloween is one of our favorites!

I used to celebrate my birthday on Halloween since it is so close, but now since Kendall's birthday is November 3rd, she has now taken over the Halloween birthday party ritual!

Check out what my mom has done so far!...

• She is going to put black fish inside that bowl on the dining room table!
  
• On the front lawn there are tombstones that make it look like a grave yard and a strobe light that flashes at night and looks like ghosts are walking through! 
• Sculls in the dining room (jeweled, of course!)
• And tons more!
  

Do you guys decorate your houses or apartments?

I am not decorating my condo because I'm not going to be home long enough to enjoy it and I really don't have the storage space for all the decorations! My mom has our entire garage filled with bins labeled by holiday!

This is me on Halloween when I was four years old. I am dressed up as Minnie Mouse!

My mom painted my face and gave me braids with a wire in it so she could shape them in loops! My mom was very creative with my hair when I was growing up.

My birthday party was always on Halloween so this picture was at my party!

Halloween is coming up—what are you going to be this year?

I'm still not sure but thinking of dressing as Cleopatra, Wonder Woman, or Princess Jasmine!  

Halloween is Reggie's bye-week, so we are trying to come up with cool costumes together. Any suggestions?
