The best part of Jennifer Lawrence's wild coat?

You can own it, too >> 

Chances are, you rely on a super basic ponytail to get you through gym class or less-than-amazing hair days, because frankly, it never fails. But this simple standby can turn into something special in a snap—and all it takes are a few easy styling touches.

Case in point: Katy Perry's totally rad 'do >>

We love Katy Perry's dramatic sleeves, earrings, braid, and lip—they give her look a "Game of Thrones"-inspired vibe!

Let your clothes do the roaring >> 

Get ready to "Roar" this Halloween!

Katy Perry's VMA boxer outfit is a cute and super easy costume to throw together at the last minute. All you need is an animal print sports bra (obviously a wardrobe staple), snazzy knee-length shorts, and striped socks.

Finishing touches include pigtails braids, an athletic tape wrapped hang, and a microphone for extra authenticity >>

Thank you, Katy Perry, for helping us kick off the weekend with a "Roar" — we're "Walking on Air!" >>

"Unconditionally,"
