If you love dressing up, then Halloween might just be your favourite holiday of the year. And while it's just around the corner, a lot of musicians revealed their elaborate costumes over the weekend, and we've chosen some of our favourites. If you've got a Halloween party coming up this week, and you still need a costume, then you better start taking some notes. These costumes are SPOOKY good (sorry).

Jhene Aiko dressed up as a Pokemon trainer, because shes "catching Pokemon not feelings", which is our new 2019 motto.
Meanwhile, Alison Wonderland was just a straight-up Pokemon.
Nina Dobrev dressed up as our fave, Billie Eilish - and we think she nailed it.

Anne Marie also dressed up as Billie Eilish - so we'll let you judge who did it better.
This couples costume from Jessica Biel and Justin Timberlake is amazing, especially because one is dressed like the other...

Demi Lovato dressed as Marie Antoniette, and absolutely nailed it.
Halsey threw a Halloween party herself and dressed up as Marilyn Manson - at another event, she donned a Cher costume, with her boyfriend Evan Peters as Sonny.
It wasn't just the celebrities having all the fun, with Lizzo and Miley Cyrus sharing some fans dressing up as her - and absolutely nailing it.
