Wednesday, May 21, turned out to be a momentous day for Irina Shayk in the style department. First, the Russian supermodel, 28, turned heads in a daring chartreuse gown on the red carpet at The Search premiere and then changed into a sheer number, exposing nipple pasties and black underwear, for a party that evening.

For the star-studded Roberto Cavalli yacht party, Shayk showed off her lean figure—and a bit more—in a sheer black gown with a plunging neckline by the designer. Luckily, the Sports Illustrated swimsuit model anticipated the full exposure—since pasties and black underwear were clearly visible.

Earlier in the day, Shayk wore another show-stopping, and more modest, gown. The chartreuse Atelier Versace dress featured an embellished bodice with a draped hood and high-slit skirt. 

Shayk isn't only sizzling on the Cannes red carpet: She and her hunky soccer player boyfriend, Cristiano Ronaldo, appear on the cover of Vogue España's June issue.
