Gossip Girl keeps getting better and better, and so do the girls' wardrobes!

Last night, Serena van der Woodsen took a traditional school girl ensemble and gave it a sassy twist with a sequined Nanette Lepore cardigan, over-the-knee tights a la Carrie Bradshaw, and a brown Botkier bag. Isn't it ironic that these ladies dress in school uniforms yet act like seasoned adults? That's why you gotta love Gossip Girl.
