From Carey Mulligan's quirky Prada gown covered with miniature kitchen utensils in 2010, Lawrence's bold red form-fitting Calvin Klein in 2011, to Rooney Mara's white structured Givenchy gown offset by jet black hair in 2012, each year one emerging actress is sure to make a fashion statement.

This year, all eyes are on "12 Years a Slave" best supporting actress nominee Lupita Nyong'o, who has so far captivated fashion critics with her vibrant color choices.

From a vermillion Ralph Lauren column gown with a cape at the Golden Globes, a turquoise figure-hugging Gucci dress with a floral detailed neckline at the Screen Actor's Guild Awards, to a jade Dior Haute Couture gown at the BAFTAs in London, the 30-year-old actress has topped the best-dressed lists.

Nyong'o's fashion hits have cast a spotlight on her stylist, newcomer Micaela Erlanger, whose savvy picks have showcased the actress' versatility, made her a fashion muse almost overnight, and helped her land a campaign with luxury brand Miu Miu.

"Having that standout moment or having that public image is really an integral part of building someone's persona," said Erlanger.

As for what the Kenyan actress will wear on the Oscars red carpet, Erlanger isn't giving any clues. She has been scouring runways at this month's fashion presentations in New York and London in search of a standout dress.

"There should be an element of surprise, and that's what keeps everyone interested. I might go for the whimsy and unexpected but keep it modern and classic at the same time," the stylist teased.
