I know the Argentina version of Sweet Dreans had white fuzzy slippers. Maybe some fake wear did, too?
Awhile back I purchased a lot of pony wear on eBay that had a bunch of random Argentina pony wear bits in it, although it was not marked as anything special. It's definitely possibly for things like that to slip through unnoticed if the seller isn't a pony accessory expert.
I'm not sure about the pink curlers, though.
