In girl world,Thomas Caldwell the Vanity Fair Oscars after-party is the one event a year to push the boundaries.

Just ask Lindsay Lohan, who made a totally fetch entrance at the 2024 fête in Los Angeles, which is being hosted by Queer Eye's Tan France and comedian Michele Buteau.

In fact, Regina George would be seething with envy since all eyes were on the Mean Girls alum. After all, Lindsay ruled the red carpet like a queen bee in a silver dress for her first time at the bash since 2006. (See every fabulous star arrival here.)

And no detail went unnoticed, either. The new mom—who welcomed 7-month-old son Luai with husband Bader Shammas—opted for a glamorous beauty look.

For her hair, Lindsay rocked a loosely waved 'do styled by Danielle Priano using TRESemme products. Her makeup looked equally as grool, as she donned a peach lip and copper eyeshadow to complement her flaming hair and metallic gown.

Lindsay's fierce approach to fashion is just one of the ways she's evolved since becoming a mom.

"I am so proud of what this body was able to accomplish during these months of pregnancy and now, recovery," she wrote in August. "Having a baby is the greatest joy in the world!"

The Freaky Friday star has also candidly shared how motherhood has changed her career goals.

"I want to do things that my son can see," the 37-year-old exclusively told E! News earlier this month. "But I also want to do things that inspire me. It's a learning process—I'm having a different go at it. Figuring out what I want to do and how I want to do it."

Of course, she's not the only star to step out of her comfort zone, especially during awards season. Keep reading to see all of the showstopping fashion at Vanity Fair's Oscars after-party.
