Brie Larson has been a standout on every awards show red carpet this season and style guru Joe Zee got the secrets behind her looks.

The Best Actress Oscar nominee stunned in a powder blue Atelier Versace gown for the Screen Actors Guild Awards last month, but fans might be surprised to know that the dress was picked the day of the show.

"We literally tried on five dresses," Larson's stylist Cristina Ehrlich told Zee. "This was the first dress we tried on, and I had just seen it in Paris the Sunday before."

Because the dress was chosen so last minute, Ehrlich had to pull out a few tricks to get the dress ready for Larson in time.

"We were in the hotel right next to the elevator [working on the dress]," Ehrlich said. "We dominated their hallway. We set up a table. We literally had three different people sewing the details."

Larson's sparkly Calvin Klein gown at the Golden Globes was designed specifically for her and seemed to be a case of love at first sight.

"When I was the most blown away was when I saw this beautiful gold thing that they had made," Ehrlich said, referring to a hoop that connected the dress around Larson's neck. "To wear a dress that's that heavy that's being supported by, like, a halter neck, it's a commitment."

The Oscars luncheon brought out a more casual side of Larson, who rocked a skirt with eyelash designs sewn on it.

"We were like, 'All eyes on Brie,'" Ehrlich explained. "That's where that came from."
