I actually got the minnie dress from my mom who bought it in Taiwan. She bought it from Creative Yoko (Pet Paradise).
They do have a store in NY called Pretty Yoko (same company). I haven't seen that dress on the website (
www.prettyyoko.com ), but if you live near that area, I'm guessing you can check it out and see if they have it in store.
I hope you'll be able to find it because it is so cute. Unfortunately, it was way too big for Mocha but it fits Sophie so well! She is such a doll!
