Lifestyle Style All of the Stylish Hair Changes Stars Debuted at the Oscars See the Oscar-nominated stars debut new hair looks at the Academy Awards By Kaitlyn Frey Kaitlyn Frey Instagram Twitter Assistant Style & Beauty Editor, PEOPLE People Editorial Guidelines Published on March 4, 2018 10:57 PM Share Tweet Pin Email The Academy Awards are one of the biggest night’s of the year for stars to make bold fashion and beauty choices on the red carpet. From Taraji P. Henson’s sheer back gown to Allison Janney’s $4 million worth of diamond jewelry to Whoopi Goldberg’s unlaced combat boots worn beneath her gown, celebrities pulled out all the stops at this year’s show. And while many actresses like Allison Williams stuck with classic old Hollywood waves on the carpet this year (an Oscars favorite!) when it came to their hair look, a slew of stylish nominees took this red carpet moment as an opportunity to debut fresh hair changes. Margot Robbie, nominated for Best Actress for her portrayal of figure skater Tonya Harding in I, Tonya, hit the red carpet in a romantic white Chanel Haute Couture gown with beaded straps and a crisscross skirt, but we couldn’t help notice the shorter textured bob she sported too.

Oscars 2018 Nominations: Get Out and Lady Bird Score Big In honor of her Best Supporting Actress and Best Original Song nominations for her work in Netflix’s Mudbound, Mary J. Blige (who also performed an emotional ballad from Mudbound during the show) stepped out with a new hairstyle. Be sure to check out PEOPLE’s full Academy Awards coverage to get the latest news on Hollywood’s big night. Blige, 43, wore her pixie pumped up with plenty of volume and teamed the new hair look with a sparkling ivory Atelier Versace column gown and Platinum by Forevermarkdrop earrings featuring 6.93 carats of diamonds.
