Lady Gaga wears clown couture at the premiere of “Joker: Folie à Deux”.

Perhaps no one is better suited to the art of method dressing than Lady Gaga. The singer and actress just showed she can pull off a role like no other by slipping into a themed outfit as a tribute to her Joker: Folie à Deux Character, Harley Quinn.

Gaga, who was in London for the film's UK premiere, wore a dramatic tailored Celine dress and matching bolero. Gaga's dress was designed in her signature color joker Character: bright cherry red. It featured a plunging neckline and elegant ruffles that hung asymmetrically over the skirt. Over the top, Gaga layered a matching short coat that also featured a sculptural design in the form of puffy power shoulders. However, what really brought Gaga's look to the forefront was her hair and makeup choices.

She ditched her famous blonde locks in favor of a jagged, cropped bob with red and black highlights. She wore a very joker-esque lip and graphic blue eye makeup reminiscent of Harley Quinn's signature glamour. She topped it off with a black manicure and a selection of Tiffany & Co. jewelry, including a Jean Schlumberger brooch and platinum and 18-karat yellow gold bracelet.

Gaga seems complete joker (She just announced a companion album due out later this week), but her first red carpet to promote the film was all about classic Hollywood glamour. For the film's debut at the Venice Film Festival, she wore a drop-waist Dior dress, statement jewelry from Tiffany & Co., and a Philip Treacy headpiece. Her hat was from Treacy's fall 2001 couture show and was previously worn by the late icon Isabella Blow.

Joker: Folie à Deux, Director Todd Phillips' musical thriller focuses on the love story between Gaga's Harley Quinn and Arthur Fleck (Joaquin Phoenix) after they fall in love at Arkham Asylum in Gotham City. The sequel contains a major sonic element, which Gaga discussed at length in a recent interview.

“It was a process that was completely rare and original for this film, and I really enjoyed working on it,” she said, adding, “We spent a lot of time talking about the voice, and for For my character, I wanted to find a voice for her that would be unique. But also because fantasy plays such a big role in the film, I also tried to use my voice like a brush and in a way that I wouldn't be required to as the singer and entertainer that my fans know me as.”
