This year's theme, "Camp: Notes on Fashion," is perfectly fitting for the eccentric pop star.
Based on Susan Sontag's 1994 essay, "Notes on Camp," the Costume Institute's new exhibition will display clothes and accessories, dating from the 17th century to the present, that explore "how the elements of irony, humor, parody, pastiche, artifice, theatricality, and exaggeration are expressed in fashion" -- meaning this year's gala is all about over-the-top fashion, which Gaga is certainly no stranger to.
The multitalented artist has been serving unforgettable -- and often controversial -- looks on stage, in her music videos and on the red carpet for more than a decade, making Gaga the queen of campy fashion.
Although her style has notably evolved -- and recently took a glamorous, elegant turn in the A Star Is Born era -- Gaga will always be known for her unapologetic sartorial choices that never fail to make a statement.
In anticipation of her third Met Gala appearance on May 6, we're looking back on Gaga's most iconic, head-turning ensembles of all time.
Lady in Red
Gaga accepted the Best New Artist award at the VMAs in 2009, wearing a sheer red lace dress with full-coverage face mask and oversized crown, designed by Alexander McQueen.
The "Shallow" singer channeled intergalactic vibes at the 2010 GRAMMYs in a sparkly, structural Armani Privé dress and yellow tresses as she held a sharp star on the red carpet.
The Meat Dress
Undoubtedly one of Gaga's most famous looks, the meat dress had everyone talking. She rocked a Franc Fernandez frock, head piece, shoes and purse made out of raw meat at the 2010 VMAs.
The musician was unrecognizable at the 2013 Glamour Women of the Year Gala, when she arrived in a platinum blonde crimped wig and white powder makeup. She wore a Thom Browne skirt suit and platform pearl sandals.
For her first Met Gala in 2015 -- where the theme was "China: Through the Looking Glass" -- Gaga made a grand entrance in a voluminous, feather-adorned black robe and matching dress from Balenciaga, complete with a glitzy headpiece and dark bold brows.
The following year, which was the last time Gaga was at the Met Gala, she looked like a total '80s rock star in a pantless Versace outfit, with a cut-out leotard, metallic circuit board-inspired jacket (the theme was "Manus x Machina: Fashion in an Age of Technology"), fishnet tights and sky-high platform boots, topped off with large, curled locks and a bright red lip.
