When you take time to think about it, it makes complete sense that stylish people befriend other stylish people. Such is the case for Sienna Miller and Poppy Delevingne, who hung together (and celebrated Poppy's bachelorette party!) at a Superdry event held this weekend in the Coachella Valley. Alike but different, both women showed off perfect examples of the festival street style we've been busily studying.

Sienna's festival look was all light and airy, mixing gold-dotted shorts with a flimsy white tank, sunglasses, and bare feet. Conversely, Poppy went dark and sultry in a high-waisted bikini brief and top, finished off with a fringed black leather Superdry jacket. Whether you're the angel or the siren in your best friendship, we're positive you'll gravitate toward one of these looks. Scroll down for more images and to see similar suggestions ready to shop.

If Sienna's high-waisted, baggy shorts feel shapeless on their own, copy her styling trick. She avoids a mumsy look by wearing them with an airy, cropped top that is boho-sexy (and flashes some skin).

The key to making Poppy's all-black look fashion-friendly (rather than Vegas-bound) is the high-waisted bikini brief. If she'd gone with a tiny string bikini bottom, the whole combo would run the risk of looking low-budget.

In true music festival spirit, she topped off loose hair with a floral wreath (we spotted a ton while examining the weekend's best accessories).

Because she's one very lucky lady, Poppy's jacket was customized on the back with her nickname.

If you weren't already craving a fringed leather jacket, we bet you are now. How rad do all the tassels look when fully extended?

Harley Viera-Newton swung by to celebrate the bachelorette, too, picking a matching slip and shirt (worn open) from Topshop. Her outfit wasn't all high street, though; that baby pink Chanel bag is worth a sigh or two.

Party guest Jackie Swerz went more Sienna's route, picking a crisp white romper and flat boots.
