There’s going Instagram official, and then there’s making your relationship public on one of the biggest red carpets in the world.

On Thursdasy, Olivia Rodrigo and Louis Partridge hard-launched their relationship at the 81st Venice International Film Festival

when the singer accompanied her actor boyfriend to the premiere of his new Apple TV+ series, Disclaimer

At the event in Italy, the two took the black-tie dress code quite literally,

matching in nearly all-black ensembles, giving serious spooky glamour.

(Beetlejuice Beetlejuice was one of the major film premieres, after all.)

For her part, Rodrigo chose an intricate slipdress from Rodarte

The spaghetti-strap piece included velvet embroidery inching across it in the shapes of roses and stems,

and the floral theme was emphasized with a silk floral pin that was attached to the top of the neckline.

In an effort to keep the look monochromatic, Rodrigo paired the dress with strappy heeled sandals and a black rectangular clutch bag

both from Jimmy Choo. She accessorized with shades from Lowercase and white gold stud earrings from Fiametta.
