If there was ever a Halloween platitude to ring true, it’s Cady Herron’s wise words in Mean Girls. “In the real world, Halloween is when kids dress up in costumes and beg for candy. In Girl World, Halloween is the one day a year when a girl can dress up like a total slut and no other girls can say anything else about it.”

One of the most iconic scenes to come out of Mean Girls (and there were A LOT), Cady’s Halloween revelation is particularly pertinent for the Hollywood set, who typically favour the glamorous and skimpy to the grotesque and ghoulish (case in point: Kendall Jenner below) for the American holiday.

Whilst the 31st is on Wednesday, the Halloween parties were rife in Hollywood over the weekend. Here, a round-up of our favourite Halloween moments in Hollywood.

Taylor Hill
OK, we had to double take (even triple) when we saw this in our morning Insta scroll. The model is testament to the transformative power of makeup and hair, undergoing a full-blown transformation as Japanese character, Sailor Moon. “I am Sailor Moon, the champion of justice. In the name of the moon, I will right wrong and triumph over evil… and that means you! #HappyHalloween”

Kendall Jenner
“Do I make you randy baby?” Yes, Kendall. You do. Clocking Halloween as one of Austin Power’s fembots, her glam team – Jen Atkin and Mary Phillips – were on hand to transform Kenny from cool brunette to bombshell blonde. Shagadelic, indeed!

Kaia Gerber
Embracing the ghoulish holiday with a little rock ‘n’ roll, Gerber became a perfectly punked-up Joan Jett with spiked black ‘do and super smudged-out kohl.

Patrick Ta
As Ta said, “Another Year Another Skull,” and of course the makeup genius created the ultimate part-human, part-skeleton.

Nicky Hilton
Now this was an iconic Halloween makeover. The hotel heiress paid tribute to sister Paris’s iconic 21st birthday – glomesh, tiara, choker and all – in one of the best Halloween outfis. “21 again tonight! 👸🏼✨✨✨PH vibes #HappyHalloween,”  she captioned the picture on Instagram. That’s Hot.

Zoe Kravitz
Zoe Kravitz turned into a rather glamorous, Seinfeld-loving vampire – albeit subtly – with just a hint of blood across her chest, on her fingers and dripping down her lips. “Rise n dine. ( night time is morning for da vamps )”

Makeup By Mario
Kim Kardashian’s go-to makeup man, Mario ramped up his own Halloween makeup with an incredible (and truly terrifying) rendition of Dracula.

“That girl is poison…” She sure is. We’re totally green with envy at Halsey’s Halloween beauty: glossy red locks, serious contour and the most spectacular emerald eyes. “Fav costume of all time ever. Also can’t believe we pulled off the gorilla / poison ivy dance from Batman and Robin. Oh yeah….we went there….”

Brad Goreski
The celebrity stylist morphed into Kimmy K with baby pink wig, oversized lens and her famous legging + sneaker combo, saying, “It’s not Yeezy being us.”

Lais Ribeiro

The supermodel took her Halloween makeup to the next level, all thanks to the meticulous handiwork of Morgane Martini. One of the more macabre makeup moments of the night, those eyes, hair and lips were everything.
