Ever since “drivers license” dropped back in 2021, Olivia Rodrigo has been taking over the damn world, and we are 100 percent into it. But it’s not just her music that has everyone obsessed (though all the tracks on Sour are undeniably bops). The Disney darling is also a total fashun queen, with a Y2K-meets-pop-punk style that’s totally her own. If you’re looking for Olivia Rodrigo costume ideas for Halloween, the possibilities are pretty much endless…but we’ve rounded up her most iconic outfits (and a whole bunch of less-expensive dupes) to get ya started.
With Halloween costumes inspired by everything from her music videos, to her award show appearances, to her immaculate street style, we’ve got all the best Olivia Rodrigo costumes to rock this year, and you better believe they include a whole lot of plaid, platforms, and pigtails. And if you’re looking for more pop culture costume ideas, fret not, ’cause we’ve got you covered there, too.
