Help Me Find a Present for My Niece!!! Disney Store Items!

[suffolkprincess]

I am looking for a Lizzie McGuire sundress, cotton stretch knit with lime green flowers and hot pink flowers (hibiscus-y.) It has spaghetti straps and is kinda short. We need it in size 8 or up. She has had it in size 6 for at least 2 years and it is her FAVORITE for the weekend but... she is not a 6x anymore. Anyone help? (and yes, I did see it on e-bay, but that seller just had size 6.)

Thanks guys!
