My daughter technically wears a toddler size 6, but I ordered her all size 7’s for room to grow. These are 7’s and they have a little room, but fit. What’s cool is how simple they are to put on, my 3 YO can do it all by herself. Just a simple Velcro strap, nothing complicated. I also love them Bc they’re glittery, but the material doesn’t shed glitter/ plastic-ish) seems like it will repel water, etc. loving these, so far! 🎀See full review
