Hollywood Reporter Names 25 Most Powerful Stylists List

The Canada-born pair — Harris now lives in New York, Welch in L.A. — created one of Oscar night’s most talked-about moments with Keibler’s gold Marchesa gown, an example of how style can help put a personality on the map (dating George Clooney doesn’t hurt, either).

Harris and Welch made quirky New Girl’s Deschanel turn heads in neon-green Prada at the Globes, as they did for last year’s red-carpet darling Steinfeld with her age-appropriate but fashion-forward Rodarte and Miu Miu looks.

The stylists also are famous for attention-getting accessories. For Wilde’s appearance at Vanity Fair’s post-Oscar party, the duo put the actress in a black Gucci strapless gown and added Van Cleef & Arpels jewels.

“The dress was so simple, but the vintage jewelry made it like sex,” says Welch. “I was like, ‘Let’s just go for ’70s Gucci sex — refined but hot.’ ”
