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!

Adorable!
Size: 7 Toddler, Color: Black
These little shoes are absolutely adorable! I got my 2 year old daughter the black sparkly ones. I originally ordered a size 6, but had to return & swap for a size 7. Not sure if this shoe runs a little small or if my daughter’s foot is just a little big. They are a soft rubber & they smell amazing (I know that sounds weird but when you receive them you will see what I’m talking about lol). They seem like very good quality & like they will last awhile, especially on a 2 year old who is hard on shoes!
