Help find pieces ??

I don't know exactly what to call this but I'm looking to make a slight custom Frankie. I wanna make a doll of her from Boo York bc it's a literal crime that we didn't get a doll of her. Pic for reference but does anyone know any fashion packs or other doll brands clothing that would match up to this I alr know what Frankie doll I wanna use but I need help for the outfit.
