Rocker Chic

The Costume Institute's exhibition will explore how fashion designers incorporated punk's D.I.Y. style into haute couture clothing. That includes the use of safety pins, which D&G used to embellish the slashed T-shirts worn by waitstaff for a party at New York's Henri Bendel store in 2001.

Guests took their turns on a mini-golf course in the yard.

During the day, the billboard above the venue entrance simply displayed the event's hashtag in black letters. As the sun went down each night, a projector mounted on a roof across the street added a 3-D display of tweets and photos that used the official hashtag.

At its Coachella party, Lacoste set up a nail art station, where guests could stop by for colorful, branded looks applied in a breezy white cabana.

In Los Angeles in the days before Coachella kicked off, jewelry brand Haute Betts hosted a party with a floral garland-making station, where guests could create their own festival-ready looks—and wear them to contribute an on-brand, boho-chic atmosphere in the party space.

Sleek signage in foliage and hedging served as chic, branded photo backdrops for celebrity arrivals.

Cigarette-style girls, clad in Lacoste gear, passed Kiel's sun protection products.

Guests played "life-size Jenga" using huge game pieces stamped with the name of the vodka brand.

In honor of the fruit-flavored vodkas, a giant board of tic-tac-toe used cutout citrus slices as pieces.
