Hogwarts is getting a darker wardrobe. Ahead of HBO’s forthcoming Harry Potter series, premium lifestyle brand Blvck Paris is returning for a second time to the Wizarding World with a grunge-leaning take on Harry Potter merch. The line transforms familiar house codes and character references into an all-black collection that feels as suited to the street as it does to the Great Hall.

The collection spans ready-to-wear apparel and accessories, including a Gryffindor sweater, Harry Potter stationery kit, Slytherin teddy hoodie, 2027 agenda diary and pieces inspired by Draco Malfoy, Nagini and Sirius Black. Some styles are available to ship now, while others are available for preorder with a ship date of Oct. 30. Shoppers can also get 10 percent off their first order when they subscribe to Blvck Paris.
