Kate is named for my very most favorite cousin in the whole world.
These beanies are intended to be worn with the brim down but the brim can be flipped up if desired. The original style/design has a floppy back/drop to it.
Size 3 is a one size fits most (big kids to adults).
Size 2 is intended for bigger babies (3/6-9/12 months).
and size 1 is for small babies (newborn to 3/6 months).
If in doubt, size up.
