Remember that our hats are stretchy, so if you love a hat that doesn't seem to be exactly the right size, it may still fit fine. This chart is just to give you an idea of general sizes. We want you to be happy with your purchase, and offer a full refund within 30 days of purchase if things don't fit right. Also, remember that your kids will grow! So buying hats that are just a hair big will mean they last a bit longer.
