Sz Small/Petite. This could be worn by petite woman or young girl. There are no stains on material. Flaws in band noted in pics. Thread looks like it could be ticked back into holes if your handy. I'm just not. Fabric is nice and stiff. Not floppy. Interior is very clean Measurements are approximate and I've tried my best to be exact. 20-inch circumference will fit comfortably 21-inch head circumference will fit snugly or on the tight side. All depends on how you wear it. From a pet and smoke free home.
