The style of those dolls is actually 'Pokedoll'. There are also slightly larger sizes, usually reserved for legendaries and massive ones that are usually starters and pikachu! c:
But a Pokedoll of Sylveon hasn't been made yet, sad to say. You could buy official pokedolls of the Eeveelution line (I do warn you in advance that some of them could be quite expensive for official ones!) but for Sylveon I would suggest finding a plush artist on DA and asking about a commission! I've seen some very cute ones already!
