I originally ordered all four pairs of tiny shoes for Penny,
--- but the two pairs of Mary Janes were too big.
Penny's misfortune is Neelie and Serenity's good luck though, as the larger shoes fit Pukifee dolls perfectly.
The 25mm sneakers I purchased do fit Nappy Choo nicely, but the tiny, 23mm purple Oxfords fit her even better, perfectly in fact!
They were a free gift from the seller* just for testing the fit on Penny!
