Marion Cotillard exudes that insouciant Parisian cool that is the stuff of girl crushes. The mention of her name around the VIOLET GREY offices (where the XX chromosome count runs admittedly high) is enough to incite a chorus of lovelorn sighs and declarations of devotion.

Of course, we’re hardly the only ones to have fallen under the comely 39-year-old French actress’ spell. Makeup artist Christophe Danchaud and hairstylist Robert Vetica have been working loyally by her side since her breakout role in the 2008 Édith Piaf biopic, La Vie En Rose (for which she won an Oscar for Best Actress). “Working with Marion is amazing,” says Vetica, noting her fashion-forward sensibility and penchant to push the aesthetic envelope. “I always feel challenged.”

Both men will be with the actress on Sunday to prepare her for the 87th annual Academy Awards. (This year, she’s garnered a Best Actress nod for her starring role in the Belgium labor drama,  Two Days, One Night.) And though they remained tight-lipped about the look they have in store for her, Vetica, at least, seems confident. “Our team knows how to own a red carpet,” he says.
