This is a 100% cotton acorn hat. I purchased it handmade. It's made with thick red yarn, giving it a plump finish. 47-50 cm I used to put it on my daughter when she was 2-3 years old, and she stood out wherever we went, and people often told us how cute she looked♪ There are no noticeable frays or stains, and I think it's in relatively good condition, but please consider purchasing only if you understand that it is a handmade and used item.
