We love this hat, perfect white hat with a matching ivory+neutral flower woven band! It has a drawstring on the inside if you need to adjust it and make it a little smaller. The fabric material is a soft faux suede that is on the stiffer side! The width of the brim on the hat itself is 3.5" wide. The circumference of the inside of the hat is 22.5” but is adjustable with the drawstring interior and you can make it smaller. Fabric is 100% Polyester. Hand wash only.
