The cast of Roma dressed to the nines and chose extremely flattering dresses that were a real hit on and off the carpet. Yalitza Aparicio, who was nominated in the Actress in a Leading Role category for the Alfonso Cuarón film, chose designer Rodarte to style her for her big night, and she looked like a true fairy-tale princess. Everything from the one-shoulder design to the color fit her so perfectly. Marina de Tavira provided the perfect contrast by wearing a gorgeous red strapless dress by J. Mendel that was an absolute dream.

There were also, of course, some misses on the carpet, and some stars who took it way too far for the award show. But if you are going to take a fashion risk, the Oscars might just be the most appropriate way to have all eyes on you. Scroll through to take a look at the best and worst dressed of the 2019 Oscars.

Yalitza has been having such an incredible fashion moment while she's been promoting Roma, and she didn't miss at the Oscars. She wore a gorgeous chiffon gown by Rodarte, and it was covered in rhinestones. The teal gown was soft and delicate and suited her perfectly.

Jennifer Lopez doesn't know how to wear a bad dress.

There might be some sort of formula for how J.Lo chooses her dresses for red carpet events. She doesn't miss! We love the fabric of this gown and that even though she's completely covered from head to toe, she's still the sexiest woman on the carpet.

Of course, Alex Rodriguez was there by her side.

And he looked just as good as his girl! Alex opted for a white-and-black tuxedo, sporting a gorgeous white blazer, and the pair were just too stunning to be true.

Marina de Tavira looked dazzling in a red gown.

The Mexican actor looked incredible in his tuxedo. When he was interviewed by Variety, he reflected how things have changed since the first time he attended the Oscars. “I’m really happy to be here this year,” he told the outlet. “I’m hearing Spanish all around, which is lovely. I’m seeing family members, you know, like people I grew up working with. I remember the first time I did this, I didn’t know anyone, I was with Gael [García Bernal]. No one wanted to interview us."

Alfonso Cuarón returned to the carpet with his squad.

Before the show she sent flowers and a sweet note to her competition in the Best Actress in a Supporting Role category: Roma's Marina de Tavira. “Congratulations! It’s a huge honor to be nominated alongside you. Have an incredible night!! XOX, Emma Stone,” the note read.
