Todd Spangler NY Digital Editor Snapchat is pinking out loud for Greta Gerwig’s “Barbie.” Warner Bros. Pictures is launching a “Barbie” AR Lens ad campaign exclusively on the social and messaging app — meaning Snapchat is the only place where you can dress up to look like Margot Robbie’s Barbie or Ryan Gosling’s Ken in fashions based on the film. The studio’s paid campaign on Snapchat launches Friday (June 30), three weeks ahead of the movie’s wide opening on July 21. Snapchat users can access the virtual Barbie wardrobe from the app’s Lens Carousel or by scanning the QR code (left). With the debut of the new Barbie Wardrobe AR Lens, Snapchatters can see themselves wearing different outfits and accessories inspired by costumes in the upcoming film. You can share the resulting pics or videos in a Snap message or a Snapchat Story (or save it to your camera roll to share via text or on other social platforms).
