Also, at MGM Studios, near the Disney Animation Studio, in a gift shop. there is an entire section.
My DD's crown cost nearly $30. She picked the 1.75 princess pins to go on the crown. She also got a veil.
DH paid for it, not sure if he paid extra for the "bag" that is designed to hold the crown "when not in use". I was afraid to ask! LOL
DD picked lavendar.
