Outdoor music festivals like Coachella are dirty places where young people like to dance in the mud, take off their shirts and, sometimes, wear horrifically offensive pieces co-opted from other cultures. One person who didn’t get this memo was Katy Perry, who opted for heels and long dresses for some inexplicable reason. You know what you can do in a long dress and heels at a music festival? Literally nothing. You may stand and get your photo taken, which is exactly what she did. But don’t worry, we’ve got Katy and 16 more celebrity hits and misses from Coachella (week one) and beyond:

Katy Perry’s outfits were totally inappropriate for Coachella

Rihanna
Okay, so we love Rihanna. She tries things that no one else will, and sometimes we love it. But you must not wear a fur coat to a concert held outdoors in the hot sun of California.

The two blonds look summery, casual and pretty at a Coachella bash. Pushing the envelope they are not, but come on, they look gorgeous.

Katy Perry's outfit just goes to show you that celebrities do Coachella different from us. Because how do you jump and scream and frolic in the mud in this? Not appropriate.

Kendall Jenner & Justin Bieber
Nope, nope, nope, we do not approve of this unholy union. We think the official line is that they’re friends, but their body language and tendency to ALWAYS BE TOGETHER seems to suggest otherwise. Fashionably speaking, nope, nope, nope. We do not ever approve of a backwards baseball cap matched with a belly-showing shirt.

Paris and Nicky Hilton are pretty much fixtures at anything with buzz, and you can tell they've really thought about their matching looks. Apart from the expensive bags (YOU WILL LOSE IT), these outfits are breezy and cute, and perfect for a festival.

And then this happened. Why did they have to turn from bohemian beauties into early-2000 nu rave kids? We loved you guys! Now this?

Katy showed up to a Coachella party in this, which basically looks like underwear, oui? Non? This outfit comes to us courtesy of Alice McCall and honestly, we could all probably do without it. Makeup? Lovely. Hair? Um sure, whatever. Overall look? No thanks.

We take it back a little. Now that's with someone other than the Biebs, her look is growing on us.

Sean Lennon looks like your typical hipster at Coachella, but what's with the intentionally blue-stained lips on Charlotte? She looks like a ghost that just ate a Smurf village.

Fergie
We don’t want to sound like prudes, but Fergie IS someone’s mom now. Not to say this means she has to nun up, but this? Seriously? She showed up to the Moet Ice Imperial at Moschino's Late Night party during Coachella in this yellow creation and we were like “yikes! Our eyes!”

Fergie
We've all been there, Fergie, but this is just a mess. First, there's lipstick smeared on your chin, and then there's the Avril-ish neck tie. And we get it, you need to give us the finger to show us your cross cuff thingy. Get some rest and take an Advil, girl.

We break from our Coachella programming to just take a moment to appreciate the return of the Gosling. Here he is at a Lost River promotional event in London. Sigh. Okay, that’s good.

Say hello to Broadway, Vanessa, and good luck with your Gigi efforts on the big stage. The dress you chose to party after your debut, courtesy of Alice + Olivia, truly becomes you.

We do not like this Sophia Kah black frock –not one little bit. We could use a little less cape business, to be perfectly honest. Not using it to fly? Then it’s unnecessary.

Kate proves she’s still the fairest in the land in Brazil at the 5th Annual amfAR Inspiration Gala. It hugs, it glows, it sparkles. It’s good. Very good.

So, somebody is taking her role as a fairy tale princess super seriously, is she not? Lily continues to channel her inner-Cinderella at the Tokyo premiere of the film. Her Elie Saab Haute Couture frock is all frills and prettiness and suits that event perfectly. We keep expecting to see glass slippers.

Every. Single. Piece. Of. This. Look. Is. Perfect. The blazer, the dress, the shoes (oh be still our beating hearts, the shoes), everything is wonderful. Love her, love her closet.
