Inside Winnie Harlow's Met Gala red carpet beauty prep

For Winnie Harlow, the 2019 Met Gala was the ultimate night of dress up.

"I get to be whoever I want to be and I actually get to be my truest self," Harlow told "Good Morning America" as she got ready for the annual fashion gala that's become one of the highest-profile nights of the year.

At 24, it wasn't even the model's first time attending.

"This year is a lot more calm," Harlow said on Monday night before the red carpet. "We've done it before, so we have a grasp on what we have to do."

Harlow interpreted the Met Gala's 2019 theme, "Camp: Notes on Fashion," by paying homage to her Jamaican roots.

"I'm going with Tommy Hilfiger for my second year in a row," Harlow said. "We've collaborated to create this amazing sheer dress that kind of emulates the look of a costume for Carnival in the Caribbean."

But before the beading, the feathers and the flare, it was just us and Winnie. The mode went through her pre-red carpet routine of jamming to some music and drinking a glass of champagne.

"I typically like to pray before big events like this," said Harlow. "On the flip side, I like to have a little glass of champagne to calm the nerves."

Harlow joined Met Gala royalty Lady Gaga, Kim Kardashian West and Jennifer Lopez, just to name a few, on the red carpet and wowed with her beaded gown and jeweled headdress.

Another style choice we loved on Harlow was that she opted for a short blond hairdo.

"I've never done this hair before and it's something that I really wanted for Met," Harlow told "GMA." "I feel the most beautiful when I have my hair done."

Same girl, same.
