The new look is a blue coat with purple velvet lining over a white blouse. Accessories include a cameo necklace and earrings.

Four individuals, dressed in a mix of casual and formal attire, walk through a misty forest with serious expressions, surrounded by dim natural light and dense trees, almost like they're headed to the Oogie Boogie Bash.

Agatha is seen wearing the outfit in the “Agatha All Along” trailer. The new Disney+ series, a spinoff from “WandaVision,” premieres on September 18.

Agatha debuted at Oogie Boogie Bash in Disney California Adventure in 2021. The witch appears on a treat trail in Avengers Campus.

Other Oogie Boogie Bash changes include the additions of Hades and Dr. Doofenshmirtz.

Watch the “Agatha All Along” trailer below.

“Agatha All Along” stars Kathryn Hahn, reprising her role as Agatha “WandaVision” head writer Jac Schaeffer returns as the show’s executive producer and head writer. The show also stars Joe Locke as Billy Kaplan, Aubrey Plaza as Rio Vidal, Patti LuPone as Lilia Calderu, Sasheer Zamata as Jennifer Kale, and Debra Jo Rupp as Sharon Davis.

The series finds Agatha powerless after escaping her containment in Westview, New Jersey. Billy Kaplan, a goth teen, breaks Agatha out of a distorted spell and begs her to take him on the legendary witches’ road, a series of magical trials that if survived, will reward Agatha with “what she is missing.”

Another “WandaVision” spin-off series starring Paul Bettany as Vision is also in the works.
