The Ultimate Backstreet Boys Concert Checklist, From Butterfly Clips to an All-White Outfit

Jasverlin Glitter Mini Butterfly Hair Claw Clips ($8)

Nothing says early aughts like butterfly clips, and they were everywhere at the Backstreet Boys show. I popped a few into the front of my hair for a little throwback moment, but fans really went all out with space buns and braided looks — total Y2K energy. The best part? You don't have to hunt them down at Claire's anymore, just grab a pack on Amazon and relive your teen-dream era with two-day shipping.
