The Worst Celebrity Halloween Costumes Of 2023

For many, Halloween is the most wonderful time of the year (sorry, Christmas!). No matter your age, there's something cathartic about dressing as someone else for a day — or a week, depending on how seriously you take spooky season. Of course, there are plenty of famous folk who fall in the latter camp, like Heidi Klum, often dubbed "The Queen of Halloween." The model hosts an annual bash in honor of All Hallow's Eve, and the celebrity Halloween costumes are often nothing short of legendary. This year, Klum donned a glittery peacock display to dazzle fans, while husband Tom Kaulitz tagged along as a hyperrealistic and slightly terrifying egg.

That said, not every celebrity costume is a smash hit. We hold stars to a higher standard — after all, they have a team of stylists at their disposal while the rest of us make do with little more than sheer ingenuity and a cluttered bathroom sink. From Adele's inexplicably brown-haired Morticia — everyone knows her hair is black, right? — to Margot Robbie's controversial "V for Vendetta" look, there was no shortage of duds to pore over this Halloween weekend. In fact, some were so unforgivably bad that we're not certain we'd classify them as costumes. So, if you're feeling the post-Halloween blues settling in already, let's lift those spirits a bit with some A-list spooky season looks that didn't quite earn As themselves.

Stars: They're just like us! It seems that late-night Instagram photoshoots with last-minute costume concepts aren't just for us ordinary folk anymore. With her lackluster Marilyn Monroe tribute for the 'Gram, complete with blurry snaps, Kendall Jenner has once again landed on our worst-dressed list. Celebrities dressing as famous figures was a huge trend for Halloween 2023, but Jenner should have left Monroe to Kim Kardashian if she wasn't going to go all out. If you plan to pay homage to one of the most iconic stars of all time, there needs to be something about your costume that sets you apart from other copycats.

It's only right to give Justin Bieber props for sporting several costumes this spooky season, including a precious "Flintstones" 'fit with his wife, Hailey Bieber. However, we're not sure what the deal was with Bieber's snorkeling situation at the annual Casamigos Halloween Party. Was he running late from a day at the beach? Or perhaps planning on taking a dip in the water after the evening's events died down? Either way, dressing as a snorkeler in Southern California is a yawn-worthy costume choice when you have a world of options at your fingertips. Better luck next time, Biebs.

If we learned anything from Halloween 2023, it's that we can't be ashamed of our own Halloween costume misses. Cringing at your nonexistent wig-styling skills from Halloween 2015? Or how about your smeared clown makeup from just last night? Never mind all that — just look at "Snow White" actor Rachel Zegler, who wore this Daphne design seemingly fresh out of a Party City bag. From the blinding shine of the synthetic wig to the matchy satin belt tied around her waist like a Christmas gift, we're utterly perplexed by the styling of this beloved "Scooby Doo" character.

There's nothing wrong with wearing an overdone costume — as long as you do it right. Poet Rupi Kaur dressed as "101 Dalmations" antagonist Cruella de Vil, an age-old option that's almost up there with witches and scarecrows at this point. From Cardi B to Lauren Conrad, countless celebs have dressed as Cruella, but that's why Kaur should have stepped up her game. Instead of the glamorous Disney villain we love, Kaur's take on Cruella felt uninspired. Take away the red gloves, and you'd be hard-pressed to tell her apart from an ordinary partygoer riding a late train home.
