We're not so keen on Kristin Cavallari's taking over one of our favorite guilty pleasures The Hills, but we can't deny that we love her uber trendy casual style. KCav was spotted on the streets of L.A. wearing a plaid Elizabeth and James shirt, Paige Premium Denim Jeans, an Alexander Wang bag, Ray Ban Wayfarers, and Christian Louboutin pumps. Yep, the reality tv star and budding actress seemingly layered her most expensive wares just for the paps. Oh well, you've got to love Kristin!
