Olivier Rousteing has dressed an extremely wide range of stars in Balmain [1], from North West to Jane Fonda. But the designer may have found his new muse in Penélope Cruz. While the Zoolander 2 actress's last red carpet look [2] was a glamorous Versace gown, this time around, she slipped into a Spring '16 kelly-green design that revealed a lot more leg.

Penélope played up her short hemline with stunning Chopard jewels, including a pair of 18-carat white-gold diamond earrings and an elegant emerald ring, and she opted for a pair of metallic Roger Vivier sandals to complement the hardware on her suede mini. Read on for further proof that this particular Balmain dress just might be the sexiest number Penélope's ever worn, and then shop for similar look-at-me styles.
