If you didn't live through the ‘90s in your teens or twenties, I’m not sure I can convey in a glorifying enough way the ubiquity, the importance, the power of a single bobby pin positioned just above eyebrow height in the hair. Whether or not you were using it to keep bangs off your face, it was a must-have hair accessory. Sure, we wore cute clips, too, but there was something about a lazy bobby pin that so perfectly captured a cross-section of the era's styles. And while Olivia Rodrigo wasn't even born yet, she absolutely nailed the look on her current trip to London.

The singer-songwriter is promoting her new album, You Seem Pretty Sad for a Girl So in Love, and on June 4, she made a stop at BBC Radio One. Rodrigo was spotted wearing a cropped, lime-green, knit vest over a black and white polka dot mini dress, as well as thigh-high white socks and black heels. The fit perfectly nailed influence 1960s mod style had on 1990s trends, worn in a 2026 way.

But what really brought it all together was one tiny detail: a bobby pin. Rodrigo's signature long hair was side-parted, with the thicker side held ever so slightly back by a little, folded piece of metal that cost maybe a few cents.
