The star, who plays Nala in Disney's live-action remake of the 1994 animated film, wore the ensemble for the 2019 Wearable Art Gala in Santa Monica, California.
Co-founded by Beyoncé's mother, Tina Lawson, and her husband, Richard Lawson, the gala is a fundraiser for the WACO Theatre Centre, a non-profit gallery and performance space in Los Angeles.
The theme for this year's event was "A Journey to the Pride Lands", taking inspiration from Jon Favreau's soon-to-be-released The Lion King.
Beyoncé shared a selection of photographs of her outfit on Instagram, providing her 128m followers with a close look at the details on her bodysuit, cape and heels.
The upper part of the singer's outfit featured a lion's face, with feathers protruding from it to mimic a mane.
Her bodysuit was adorned with gold sequins, while her gold heels were designed with fringed straps.
The post currently has more than 1.7m likes, and has garnered many praiseworthy comments.
"Omfg looook at this queen! I'm just dead," one fan wrote.
"The level of EXTRA ugh her MIND," another remarked.
Beyoncé also shared a video of her seven-year-old daughter Blue Ivy singing the "Circle of Life" while wearing a multi-coloured headdress and yellow dress.

The recently-released full trailer for The Lion King provided excited fans of the original film with an extended look at Favreau's new vision for the story.
The trailer shows a grown up Simba, played by Donald Glover, reconnecting with Beyoncé's Nala, just as the characters do in the original to Elton John and Tim Rice's "Can You Feel The Love Tonight".
In early April, Disney premiered new footage from the film at the Las Vegas ComicCon.
