Halloween is one of the few times of the year when you may let your guard down and become someone or something else.

Whereas it may seem customary to transform into something horrifying or frightening, celebrities all over the world have taken on roles ranging from life-sized versions of toy dolls to superheroes and even fellow celebrities.

As a result, it’s no surprise that the Kardashians have invested heavily in fright night.

Kim Kardashian West and Kylie Jenner went all out for the spooky celebrations, with more costume changes than a Beyonce concert.

1. Kim Kardashian

Kim chose a 90’s classic for the evening after wearing something a little more revealing for Victoria Secrets.

Kim dressed up as Pamela Anderson from Baywatch, with Motley Crue (whose drummer is Pammy’s alleged partner Tommy Lee) delivering the soundtrack to some Instagram story pouting.

2. Kylie Jenner

Kylie and daughter Stormi showed that clouds don’t always have silver linings with a golden-colored attempt, not wanting to cast a damper on the evening.

3. Justin Timberlake

It doesn’t get much better for family fun than dressing up as Justin Timberlake on Halloween night.

Silas, three, stole the spotlight as Batman, with the rest of the family costumed as characters from The Lego Batman Movie.

“They got candy?” Justin captioned the Instagram post, and his take of Batman’s sidekick, Robin, appears to be a Halloween hit.

Jessica Biel’s blocky Harley Quinn pushed him into the background, proving that having Lego hair can still work.

4. Jessica Alba

There was only one way for the Alba family to celebrate their first Halloween as a family of three, following the birth of son Hayes.

5. Jenna Dewan

There’s nothing like a Halloween angel to bring a smile to a frightful night’s gloom and horror. Channing Tatum’s ex-girlfriend flaunted her ‘inner self’ in a costume that would make Tinkerbell envious.
