Hi there, Irismae! Thanks for bringing your question to the Disney Parks Moms Panel!
Minnie ear headbands are certainly popular in the parks and it seems that I add a set to my personal collection every trip. I know I have seen many different variety of Minnie ears sold in the parks, but they have particularly been the sequined versions. Have you seen the rose gold variety that is all the rage right now? They are so cute! You might have luck finding what you are looking for at one of the
Mad Hatter locations in Disneyland Park or at
World of Disney in the Downtown Disney District if you will be at the parks soon.
If you are planning your head wear for a future trip, then I suggest checking the
Shop Disney Parks website or app. I did a quick search for "Minnie ears" and it looks like the Shop Disney Parks has a set in the style you describe. The ears are a soft plush and the bow is the classic red with white polka dots. They have a few Minnie ear hat options as well. You can buy these ears directly from the app or online and have them shipped to you for a future visit to the Disneyland Resort. Shop Disney Parks also has oodles and oodles of other park merchandise that you might want to peruse as well.
I hope this helps! Happy shopping!
