Halloween is one day of the year when boys and girls get the chance to resemble their spirit animal or their idol. And while most kids run around the neighbourhood on this day, Hollywood celebs throw grand parties and ensure that elaborate costumes are picked out for their kids.

In case you're wondering how to dress up your little one this Halloween, take a look at costumes that have been tried and tested by celebrity babies. But just to be sure, kids look cute in anything as long as they remember to smile.

Mariah Carey's family loves Halloween and it's evident in the several pictures that always make it to their Instagram accounts. This year, the family already attended its first Halloween party and it looks like the singer's son, Moroccan, decided to dress as Mario, the video game character every 80s kid knows about.

It looks like Chris Brown's daughter Royalty has more than one costume for Halloween 2016. In Chris's recent post, the two-year-old is seen wearing a pink princess costume that's fit for a 21st-century queen. Royalty's pink gown includes patchwork and is worn over a long-sleeved pink top. No wonder the rapper captioned the picture: "Next generation!!! Females and queens of the future."

Kim Kardashian's daughter, North West as Elsa

Kim Kardashian's daughter North West has the cutest Halloween costumes. If baby North looked like former Vogue editor, Andre Leon Talley once, she and her cousin Penelope Disick dressed as skunks the next year. Both of these looks are easy to obtain and are classics. After all, who doesn't like Princess Elsa?

Beyonce and Jay-Z's daughter, Blue Ivy, already has swag. In 2014, Beyonce dressed her 3-year-old as the King of Pop, Michael Jackson. The look was complete with a red Michael Jackson military jacket, aviators, a hat and shiny white gloves. And, of course, she was armed with a pink microphone.

Chrissy Teigen's daughter Luna as a Chef

I have dreamed of this day!

Although Chrissy Teigen hasn't revealed if baby Luna will indeed don a Halloween costume, she did give us a great idea when she placed a chef's hat atop her daughter's head. If your kid is fascinated by the culinary arts, he/she could dress up as a celebrity chef and bark orders at a party. But we wouldn't really recommend that.
