16 Throwback Halloween Costumes Every 2000s Girl Will Love

October is already upon us. Arguably the best time of the year, this month is filled with scary movies, crisp weather, pumpkins galore and giant leaf piles waiting to be included in basic AF selfies. Most importantly, Halloween is right around the corner. Not sure what to go as yet? Don’t sweat it. If you love all things 2000s, then these nostalgic costume ideas are perfect for you. 

1. Avril Lavigne 

Who wouldn’t want to be a punk-rock skater girl?

6. Cheetah Girl



“Cause we are sisters, we stand together. We make up one big family, though we don’t look the same. Our spots are different, different colors. We make each other stronger, that ain’t never gonna change.” ? • • • Had the BEST Cheetah-licious time laughing it up with @domdivadoesit, @finfelicia, and @milliemousemagic!! I think the best part of our day had to be when some strangers walked by and asked who we were and we screamed “THE CHEETAH GIRLS!” and they still looked confused ? Who’s your favorite Cheetah girl? I always loved Dorinda because she seemed the most down to earth out of all of them! ? • • • ?: @kevintsengphotography (and @therealcosbo for helping us out with video and dance moves!) • • • #disney #disneyland #disneybound #disneybounding #disneybounder #disneyaddict #disneystyle #disneyworld #waltdisneyworld #disneyig #annualpassholder #disneymagic #disneyfan #disneyfashion #disneyoutfit #disneyblogger #dressedindisney #disneyootd #styledbymagic #abc7eyewitness #happiestplace #cheetahgirls #galleria #aqua #dorinda #chanel #dcom #disneychannel
