Year after year, celebrities crowd the VIP section at the Coachella Music and Arts Festival in Indio, California, slipping into their quirkiest warm-weather outfits for this music-lover's paradise.

Katy Perry—who once attended Coachella in a several thousand dollar Louis Vuitton dress—decided to let it all hang out in a completely sheer floral frock worn over old-school granny panties and a matching bra. A leather jacket and decidedly unsexy motorcycle boots failed to make this look any more modest.

Katy Perry's BFF Rihanna treated the crowd to a surprise performance during Calvin Harris' set, shimmying about in a pair of dangerous denim shorts (so tight we fear for her circulation), a black "PEACE" sports bra and a Chanel windbreaker. That's just how she rolls.

Lindsay Lohan looked like she was having trouble finding her footing in her insane lace-up platform booties, an odd choice for anyone hoping to remain vertical throughout the day. But the shoes did match Lohan's little lace dress quite nicely.

Katy Perry was a one-woman '90s revival with her bright purple hair and floral mini dress worn over ripped stockings. Somewhere, Courtney Love is seething over the appropriation of her seminal look.

Vanessa Hudgens exercises zero restraint when it comes to these events. The former High School Musical star looked like she was in costume for a Dazed and Confused remake for most of the weekend, thanks to her headdresses and myriad '70s accessories.

Fergie's multi-layered Coachella ensemble was... puzzling. The Black Eyed Peas singer slipped a sequined vest with some billowy white train over what appeared to be a shredded black romper, while her husband Josh Duhamel looked considerably less ridiculous more low-key in a shirt and jeans.

Socialite-turned-professional club kid Paris Hilton was not interested in flying under the radar, as evidenced by her neon coral minidress and matching hair extensions. Hilton kept safe from the sun under a floppy black hat and cheesy white sunglasses.

Lauren Conrad pulled a pair of Hunter rain boots on over her floral print jeans to avoid any rain-related wardrobe incidents. The former reality star was considerably more put-together than most of her fellow celebs in a filmy white blouse and a luxe knit sweater.

Fergie tackled festival fashion with the same boho spirit as Vanessa Hudgens, throwing a leather fringe vest on over an expensive-looking cream sundress. Aviator sunglasses, heaps of jewelry and a pair of cropped Western boots finished off the look.

Emma Watson,who was spotted cuddling with new boyfriend Will Adamowicz, kept warm in a vintage-looking fuzzy jacket thrown over an embroidered blouse and black jeans. The beautiful Brit is sporting lengthy hair extensions for the upcoming film Bling Ring.
