It doesn't take a super sleuth to know that one of the best parts of Mysteryland -- or any festival -- is the fashion.

Trend: Pineapples

Yes, there were kooky costumes, furry boots and kandi clad ravers, but the top trend at Mysteryland this year? Pineapples. Maybe people were inspired by the giant pineapple tent at the festival? Just sayin'. Let's see who rocked this look:

Jessica, a Hawaii-born-Brooklyn-transplant, brought the aloha spirit with her look...

...She called it "Pineapple Pleasure."

Rob romped around in these pineapple spandex tights and a shirt that said 'Pineapple Gang'...

...He called his look "Boat Swag."

Then there was Nicolas...

...He was like, the happiest human pineapple.

Chelsea and Zach came up from Queens to flaunt their pineapple flair...

...They called their look "Pineapple Express."

Oh yeah, and here I am, with a pineapple iphone case...

...I'd call my look pineapple emoji hippie.

Trend: It's A Zoo Out There

The animals were out to play this year. Festival goers brought their fiercest, fluffiest looks to the scene. Check 'em out:

Amann and Eve brought some edge to this ensemble...

...They called their look "spooky but playful" and "accessible but otherworldly."

Matt from Poughkeepsie was posted in a field with this inflatable pool toy...

...he called his look "Inflatable Silliness." Major props.

Then there was taco cat...

...just purrfect.

Rhiannon, Danielle and Mikey were the epitome of #SquadGoals...

...They call their look the "Galaxy Wolves."

Christopher, Rebecca, Krystal and Igor brought the Poképower...

...Rebecca said their look was "Independent." Salute, girl.

Amy was basically a mermaid from Brooklyn...

..."I just went with it," she said of her look.

And finally, Casey, Andrea and John kept the Woodstock vibes alive.

Totally bohemian, and with a cool beanie to boot.
