It's the music festival that's become synonymous with fashion - and we could see why as Coachella 2011 kicked off this weekend.

Katy Perry had the 70s vibe down as she showed off a cute floral headband teamed with a cream lace belted maxidress, and she was also spotted letting her hair down in 60s-style white sunnies and a red checked cropped top.

Kelly Osbourne posed for pics in her cute 50s-style wrap dress, which she teamed with socks and boyfriend shoes, as well as a fedora and hot pink lips.

Kate Bosworth was also spotted in a cool stars and stripes number, while Transformers star Isabel Lucas rocked that hippy chic too in a dip-dye maxidress and headband.
