Hiromasa Yonebayashi pays tribute to the Studio Ghibli movies in all of his work, and When Marnie Was There is chock full of them. Here is one easy riff for fans: Anna is wearing the same hat as Mei in My Neighbor Totoro. However, I was also reminded of Taeko's hat in Omohide Poro Poro. Maybe that's just me, or maybe it's intentional. You be the judge.
