Also in attendance at Midler's party was designer Marc Jacobs, who dressed as a female bodybuilder - complete with a six pack bodysuit, Christian Louboutin heels and a tiny blue bikini.

At a Los Angeles party, Kylie Jenner and boyfriend Tyga dressed up in iconic outfits from the early 2000s, attending a Los Angeles party as Christina Aguilera from her Dirrty music video and as rapper Juelz Santana.
A night before that party, the pair kicked off Halloweekend on a more intimate note, throwing a 'Dead Dinner' for their family and friends.
The couple was dressed up accordingly as a skeleton.

Meanwhile Jenner's sister Kourtney Kardashian went to Tyga's party at Bootsy Bellows as a classic zombie bride.

Amy Schumer went with one of the most popular Halloween costumes this year, dressing up as Dustin from the Netflix show Stranger Things while her boyfriend Ben Hanish coordinated as the character Eleven.
No one's costume has gone more viral than Perry's herself, who dressed up as her idol Hillary Clinton and had boyfriend Orlando Bloom disguised as Donald Trump.
Actor Leonardo DiCaprio didn't put quite as much effort into his own costume for Kate Hudson's affair, simply donning a simple wolf mask for the costume party
