Each idea below breaks down the key pieces, where to thrift them cheaply, and the styling details that separate an authentic 00s look from a generic throwback. Whether she lived through the era or just loves the aesthetic, these costumes are fun, instantly recognizable, and easy to assemble from thrift stores. From pop princesses to Myspace emo, here is how to do Y2K Halloween right.
1. Britney’s Schoolgirl
Britney’s schoolgirl look from her debut video is the defining 00s Halloween costume, and it is simple to recreate. She needs a white button-down shirt tied at the waist, a gray plaid mini skirt, and knee-high socks with Mary Janes or sneakers. Two high pigtails with pink pom-pom ties and a backpack complete the look. The styling tip is the details: the tied shirt, the pom-poms, and the slightly undone uniform are what make it Britney rather than just a schoolgirl. This suits women who want an instantly recognizable pop-culture costume with playful energy. Thrift stores carry plaid skirts and white shirts for a few dollars. It is comfortable for dancing and works for all ages who grew up on 90s and 00s pop. Friends can join as fellow pop stars for a full TRL-era group.
2. The Paris Hilton Heiress

The styling tip is the catchphrase energy: “That’s hot” delivered with a bored expression sells the character better than any accessory.
