Billie Lourd wore a Princess Leia dress to Carrie Fisher's Hollywood Walk of Fame ceremony

• Carrie Fisher was honored with a posthumous star on the Hollywood Walk of Fame on Thursday.
• Her daughter Billie Lourd accepted the award on her behalf alongside Mark Hamill.

Billie Lourd paid tribute to Carrie Fisher with a custom dress on Thursday.

Fisher was awarded a posthumous star on the Hollywood Walk of Fame on May 4, which is known as "Star Wars" day to fans of George Lucas' universe.

Lourd accepted the award on her late mother's behalf. Fisher died on December 27, 2016, and her mother Debbie Reynolds died just two days later.

Fisher was best known for playing Princess Leia in "Star Wars," and Lourd appeared alongside her in "Star Wars: The Force Awakens" before Fisher's death.

So it was fitting that Lourd attended the ceremony in a "Star Wars"-themed dress.

Lourd wore a custom Rodarte gown to the ceremony, as the brand shared on Instagram.

Rodarte released a line of "Star Wars"-inspired gowns in 2014, and the brand said in its post that Lourd's look was an addition to it.

The black, sparkly bodice had a V-neckline that tied in the center and created a circular cutout. The dress cinched just under Lourd's chest, and the skirt was embossed with a photo of Fisher in costume as Princess Leia.

Lourd paired the dress with drop earrings, open-toed heels, and jewels on her eyes for an otherworldly look.

Lourd's nails were painted to honor "Star Wars" too, with several of her nails painted black and adorned with stars.

Her middle fingers were painted with illustrations: one featured a drawing of Princess Leia's face, while the other had the starbird symbol the rebels used in the films.

Jamie Mizrahi styled Lourd's playful and sweet look.

Lourd celebrated her mom alongside Fisher's "Star Wars" costar Mark Hamill, as well as the droids from the film series, C-3PO and R2-D2.

In 2018, Hamill asked "Star Wars" fans to campaign for Fisher to receive her star on the Walk of Fame early, as he wanted her to have it by the time "Star Wars: The Rise of Skywalker" was released.

Lourd's father, Bryan Lourd, and her husband, Austen Rydell, were also by her side during the ceremony.

Lourd did not invite Fisher's siblings to the ceremony, which she confirmed to The Hollywood Reporter after Fisher's siblings spoke to TMZ about Lourd's decision.

"Days after my mom died, her brother and her sister chose to process their grief publicly and capitalize on my mother's death, by doing multiple interviews and selling individual books for a lot of money, with my mom and my grandmother's deaths as the subject," Lourd said in her statement.

"I found out they had done this through the press. They never consulted me or considered how this would affect our relationship," she added. "Though I recognize they have every right to do whatever they choose, their actions were very hurtful to me at the most difficult time in my life. I chose to and still choose to deal with her loss in a much different way."

Lourd and Rydell welcomed their son, Kingston, in September 2020.
