Our smallest size is 3, and our largest is 12. We utilize blended sizing for the majority of our clothing, so in our line you'll find pieces that are size 3, 4/5, 6/7, 8, and 10/12. Our blended sizing is the average of the 2 sizes.
To break it down another way...
XXS - 3
XS - 4/5
S - 6/7
M - 8
L - 10/12
If your kids are in between sizes, we recommend sizing up!
