Lady Gaga [1] may still be promoting House of Gucci [2], but she's toned down the dramatic style [3] she repped on the movie's recent press tour [4]. Still, toned down certainly doesn't mean boring. For an appearance on Jimmy Kimmel Live on Monday evening, the multihyphenate wore a unique take on the classic little black dress, a glamorous creation [5] from Christian Siriano's pre-fall collection, to chat about her portrayal of Patrizia Reggiani [6].

While the base of her look is a simple strapless LBD, the minidress features billowy, ruffled organza sleeves, giving it an almost cape-like appearance. The sleeves are removable, but Gaga of course opted for the drama. Styled by Sandra Amador and Tom Eerebout, she paired the designer piece with Dita cat-eye shades, Giuseppe Zanotti patent leather pumps, and diamond and gold jewelry by Kat Kim.

"Walking into the week just feeling fabulous!! @ladygaga in Siriano is just divine! 🖤🖤🖤" Siriano shared on Instagram [7] alongside a photo of Gaga's dress. Ahead, see more photos of the actor doing her look justice with a series of fabulous poses.
