Dakota Johnson returned to Studio 8H this weekend to host Saturday Night Live for the second time — and she did so in style!

The Madame Web star, 34, delivered her hilarious monologue outfitted in a chic black Tom Ford jumpsuit that featured cut-out detailing from the neckline to the waist and a black belt with a gold buckle. To accessorize, Johnson sported several bangles and a ring from the jewelry brand Verdura. She finished off her look with a pair of gold hoop earrings.

Johnson also took part in a number of sketches throughout the night (that saw her in all manner of costumes!), including a skit that joked about America's Stanley Cup craze and a fun Shark Tank recreation that included two surprise guest star sharks: Mark Cuban and Barbara Corcoran.

The actress then wore another head-turning look to the show's afterparty. She stepped out for SNL's post-show bash in New York City to celebrate the show going off without a hitch — and with endless laughs — in a jaw-dropping look to end the night.

For her afterparty attire, the actress sported a sheer, floor-length black gown that she teamed with a cropped, black furry jacket. A black purse with a silver handle and black heels finished off the elegant look.

Johnson was joined at the SNL afterparty by a host of stars, including Jimmy Fallon, who had appeared on the show during her monologue, to introduce one of the musical guest Justin Timberlake's performances and in a fun skit.

Johnson's mom, Melanie Griffith, her ex-husband Antonio Banderas and actress Demi Moore also attended the bash.

Johnson has been wowing her fans all week with her sleek looks. For SNL promo, she and her stylist, Kate Young, have been choosing subtly sexy pieces that show off the actress' curves. In one hilarious promo video earlier this week, Johnson wore a body-hugging black leather skirt and a sheer ruched black top that also clung to her like a second skin.

In yet another promo spot, this one with this week's musical guest Justin Timberlake, Johnson wore a little black dress — but it was anything but basic. The sleeveless minidress, much like her look for her monologue on Saturday night, featured a dramatic cutout across her chest, offering a racy peek at her skin.

But perhaps Johnson's most stunning outfit choice this whole promo week was what she chose to wear for The Tonight Show Starring Jimmy Fallon on Monday. Sticking with the same all-black color palette, she wore yet another little black dress, this one a strapless black mini by Wardrobe.NYC. She wore it over black tights and capped it off with black heels.

The pièce de résistance, though, was her necklace.

Around her neck, Johnson wore a Belperron Toggle Torque Necklace with an "old mine brilliant cut fancy light-yellow diamond weighing over 65 carats," the brand wrote on Instagram.

The necklace silhouette is one of the jewelry brand's most iconic pieces, dating back to the 1930s and seen on the likes of Elsa Schiaparelli.

"Designed as a slim lacquer cord, fastened around a pavé diamond button, the Toggle Torque Necklace marked a groundbreaking chapter in Madame Belperron’s career, an era defined by the confidence of an artist with newfound creative freedom," the brand also wrote on Instagram of the iconic piece and its history.
