I'm back from hiatus and am continuing the sizing down of my 43 year collection of distinctive hats - many never worn with tags, some never worn without tags, and others worn once, such as this gorgeously crafted 1990s Carol Carr hat with a nautical beachy theme. The straw has a tone-on-tone, weathered vibe and a spectacular wired scalloped brim. The hat measures 17 inches front to back and 16.5 inches side to side. While my head measures 21.5 inches and the sweatband circumference is also 21.5 inches, this hat is loose on me because of the deep crown.
