insiders: school of seven bells

Alejandra and Claudia Deheza might be two-thirds of the breathy pop group School of Seven Bells, but their iconic sleek styles are becoming almost as identifiable as their signature vocals.

We joined the twins on a shopping trip to the Williamsburg boutique OAK, where they could stock up on a few essentials before they hit the road on tour this fall.

Since the sisters usually stick to a color scheme of black and white both onstage and off, they consider OAK the perfect one-stop shop.

Claudia snagged a pair of metallic black flats and a pair of aviator sunglasses. Alley didn't buy anything because she said she already has more than enough OAK in her closet (want proof? The black and white striped tank she was wearing was still in the store, and she also owns it in two more colors!).

After living in NYC for the past 11 years, the girls have found several local under-the-radar shopping favorites, including Alter and Lower East Side men's shop B.Blessing.

And their dream brands? For Alley, it's Ann Demeulemeester, and Claudia's obsessed with Proenza Schouler.

Although the sisters admit their style has evolved since they first formed School of Seven Bells with Benjamin Curtis back in 2004, in many ways they've returned back to their old fashion ways.

Case in point?

According to Alley, "when the band started I was really into wild tribal prints, but now I've gotten back to my roots, my gothic roots. And I'm glad."
