The 10 Best Instagrams of the Week, From Flower Crowns to One Killer Ab Workout

The week's most mesmerizing celebrity Instagrams include a jaw-dropping belly dance workout and the prettiest take on festival hair yet.

Scene-stealing embellishments were the antidote to a lineup of otherwise laid-back looks this week, with bauble-bedecked hair clips, towering flower crowns, and pressings of sparkle ensuring more than a few double takes on Instagram. The creative gauntlet was thrown down by FKA twigs, who executed an impromptu belly dance that was nothing short of mesmerizing—thanks, she said, to a little help from her uterus.

For Arlenis Sosa, a beachside sunset inspired a seaward game of soccer—the ball balanced like a planet between her toned graceful arms—while Bella Hadid's backseat lean was defined by a 90s-inspired headband and crystalline blue gaze.

Alexa Chung offered a glimpse at the technique behind her trademark cat eye liner, this flick accompanied by a set of skyward lashes, as elsewhere, a constellation of refractive crystals—pressed from lashline to brow by makeup pro Violette—played against Josephine Le Tutour's natural freckles.

And while Pernille Teisbaek's pearl barrette offered the ultimate pin-back to accompany autumn's sweaters, Adut Akech Bior's extravagant bouquet of a headpiece—secured by Guido Palau on set for Moschino—proved that it doesn't need to be festival season to indulge in a little well-timed flower power.
