No one is as unbothered and unstoppable as Zendaya on the red carpet.

Continuing her Challengers press tour, the actor attended the film’s premiere today in Rome at Cinema Barberini, where she channeled Italian glamour in a magnificent white skirt suit.

The icy-white ensemble was custom-made for her by Calvin Klein and composed of a sleek blazer with structured shoulders, and a floor-length skirt with a high slit on one side. Zendaya wore the blazer open, with no top or bra underneath, rather a white gold Serpenti Viper necklace from Bulgari encrusted with white demi-pavé diamonds that wrapped around her neck and slithered down her chest.

She wore large diamond studs on her ears and even more on her fingers, in the form of twisty Bulgari snake rings in white gold, to match her necklace.

In a contrast to her frosty outfit, she looked lovely in warm bronze makeup including a peachy blush. She wore a glossy baby-pink manicure and had her hair styled in an elevated updo.

Earlier in the day, the Euphoria star attended a photo-call for her sports movie (which premieres April 26) in the most electric tennis-inspired custom Loewe look. It was composed of a silver tennis minidress dotted with hundreds of rhinestones, plus the most fun white sandals with fluorescent tennis balls skewered onto the stiletto heels.

Previously on her press tour, Zendaya—with the help of longtime stylist Law Roach—has worn a glittery green Loewe gown with a silhouette of a tennis player stamped on the front, a green-and-white checkered jacket dress from the Louis Vuitton, a shiny satin co-ord, and a gauzy white dress.
