Description/Profile - Please Read Women's Hat Hat Sunshade Foldable Hat Beige 100% Cotton Mesh lining inside No size listed, but I think you can adjust it with the string at the back. Measured around the head of the hat, it's about 48cm. (Please note that I may have measured incorrectly) I bought it for travel and wore it once because it can be folded and carried in a bag. Then I home-cleaned it, so there is some fuzzing. For those who understand that this is a used item stored at home, Simple packaging.
