Finally,after 6 month of use Zutano's Hats i can give clear review(which i could find to relay myself when i was buying it).
These hats have special kind of fit (if i can say it that way).
Generally they've been reviewing as running small,but it's not true.
Ok-let's make it clear! If you want that classic baby hat fit(and look) with rolled up edge-go for a size up,but how i understood for myself Zutano's hats are meant to be wearing without the rolled up edge-then you go for a normal size.
I ordered i size up-so my son was wearing them with rolled up edge last fall and wears same hats this spring without the rolled up edge.
One more tip-stripy hats are more stretchable,than printed ones.
