We heard Carly Rae Jepsen’s “Call Me Maybe” hit more times than we really needed to this summer—but that’s OK because we maybe liked it (OK, OK, it’s catchy!). And as she gears up to release her first album, we’re taking a closer look at this Canadian starlet’s style. Her look in one word is quirky, and she uses her accessories to express her pop persona. From neon-tipped loafers to a chainlink vest to a fruit-friendly Kate Spade clutch (shop it for $239 on neimanmarcus.com)—click through the gallery to see her most interesting accessories to date, no maybe about it.

Today is Demi Lovato’s 20th birthday!

No Doubt is back—and in a big way! The group performed their new hit “Settle Down” at the Teen Choice Awards, with Gwen Stefani’s signature red lip taking center stage. If you want to create a similar look, make like the singer and layer your products for extra staying power. “I start with a matte lipstick that’s really dry, then I put a more moist, creamy lipstick on top,” the star once told InStyle. “And my trick for not getting it on my teeth? Be really careful!” Get started by picking up L’Oreal’s Infallible Lip Gloss in Red Fatale ($10; lorealparisusa.com), which Stefani used for the “Settle Down” music video.
