Though Halloween doesn't officially arrive until Thursday, the weekend leading up to Oct. 31 was packed with festivities in celebration of the spooky holiday. Our favorite fashion people dressed up in their best and most over-the-top costumes, from Stormi Webster as Kylie Jenner at the 2019 Met Gala to Jessica Biel as *NSYNC-era Justin Timberlake — curly-haired wig and all.
Billie Eilish proved to be a popular inspiration this year, with Nina Dobrev donning the singer's signature bright green roots and Jameela Jamil wearing an Eilish-approved baggy ensemble as well. Elsewhere, celebrities concocted their own versions of other pop icons: Lisa Rinna recreated J.Lo's viral Versace look, and Kylie Jenner and and her best friend Anastasia "Stassie" Karanikolaou paid tribute to Britney Spears and Madonna at the 2003 MTV Music Video Awards.
Below, we've rounded up Halloween looks from the 2019 celebrations so far. Be sure to check back, as we'll be updating this post with more looks as they keep coming over the next few days.
