Love the style- sizing is a bit tricky online
Mini Melissa shoes always deliver on cuteness (and comfort). That said, each pair seems to be slightly different in terms of sizing! We ordered a size 2 and found that it was a little bigger than a recent size 2 we'd ordered. Still worth it, just a heads up that this might be a better purchase in person when you can try on!
