We had to bring this to your attention, although the movie is not necessarily purely about 'bling', it sure is entering!

In Sofia Coppola’s The Bling Ring, a crew of L.A. high-schoolers embark on a burglary spree in the Hollywood Hills. They target the homes of, among others, Paris Hilton, Lindsay Lohan, Audrina Patridge, Megan Fox, and Rachel Bilson. They thrill at their proximity to the celebs (yet bizarrely discard a love letter found chez Orlando Bloom). Their haul in designer loot is enough to make law-abiding fashionistas in the audience salivate.
