Our Essentials Knot hat is not only sweet, but also adjustable! Simply undo the knot and re-tie further down or up the hat to make it smaller or larger. Hats and beanies are a necessity for newborns all year around, but especially for Winter babies. We recommend at least 2-3 hats to start off your wardrobe. If the hat is still a little large, you can fold up the ribbed band for a smaller fit!
