First in the press circulation was the UK premiere of Joker: Folie à Deuxtook place in London last week at Cineworld Leicester Square. Lady Gaga wore a dramatic red dress with a slanted waist and matching puff-sleeved bolero – the look was designed by Hedi Slimane for Celine. Her dyed dark auburn hair was styled in a blunt bob with bangs, and the makeup was reminiscent of Harley Quinn’s, with bleached eyebrows, bright blue eyeshadow, and a fake, makeup-smeared crystal teardrop running down her upper cheek.

All of Gaga’s jewelry was from Tiffany & Co., including a Jean Schlumberger by Tiffany Bird on a Rock brooch, a Vigne ring, and platinum and yellow gold earrings with yellow diamonds.

Gaga’s fiancé, Michael Polansky, accompanied her in a Hedi Slimane suit.

Gaga wore a full costume for a fan event at the Nomad Hotel later that same day. She wore two looks. The first was a jersey on which various cartoon and photographed faces were collaged and quilted. She paired it with ripped red tights, matching multi-colored ruffled thigh-high socks and knee-high Mary Jane-inspired ultra platform boots. The outfit was designed by Central Saint Martins graduate Ida Immendorff.

The second fashion outfit was a striped dark blue and cream silk dress with puff sleeves. She paired the dress with Harley Quinn-style diamond-patterned tights and black platform shoes.

The next day, Gaga opted for a more understated look in a black and white vintage dress with a lace collar. The look was tailor-made by costume house Muto-Little. But Gaga added a twist with knee-high striped socks and chunky platform buckled ankle boots.

This week, the actress traveled to Los Angeles for the film’s premiere at the TCL Chinese Theater. At some point, she increased her hair color, changing from auburn to a bright cherry red. Gaga wore another dramatic Hedi Slimane dress for Celine. This piece was black with dramatic ruffled sleeves that merged into a cape on Gaga’s back. The dress featured a high slit up the side, which showed off sky-high pointed platform boots.

Gaga paired the dress with other jewelry from Tiffany & Co. This time, she opted for the brand’s Schlumberger Vigne necklace, which contains a total of 330 carats of oval rubellites. In her ears, she wore Tiffany black enamel platinum, diamond and 18-karat yellow gold earrings designed by Schlumberger.

After a busy week, Gaga was finally spotted leaving in a relaxed outfit Jimmy Kimmel Live!, where she spoke and performed with Kimmel. Her hair was slicked back and dyed her usual blonde. She wore sheer black tights, an oversized Jimmy Kimmel Live! T-shirt, an oversized black blazer and gray peep-toe pumps.
