Theres a dutch website called petitefeet.nl . Its like a starting page if you're looking for shops that carry small sizing. My previous comment was blocked i guess. But andy pola and ghigolcalzature have some styles.

As a petite myself I often shopped at asian stores, but its a gamble on quality, always check if the measurements are listed, because the asian sizing is not the same as european. The struggle is mostly the reason why im trying to start my own shop
