Sweeney mastered sultry elegance in this black strapless number from Schiaparelli that featured sheer panels and layered ruffles down the length of the dress.
The actress arrived at the 2023 Met Gala in a blush pink gown by Miu Miu that was dripping in romantic details, including crystal embellishments, a black bow on the skirt, and a dramatic train.
Sweeney rocked a completely different Miu Miu look (including a hair color change) at the premiere of her film Reality at the Berlin International Film Festival.
For the Emmys, Sweeney wore a light gray Oscar de la Renta gown with a column silhouette, sparkling floral appliqués, and a bustled train.
Switching it up for the Emmys after-party, Sweeney opted for a sleek and sexy dress by Versace in a gorgeous emerald green hue.
The actress made her Met Gala debut in a white Tory Burch gown with a corset bodice, a peplum waist, and a detachable skirt.
