I LOVE FANCY DRESSBrown Explorer Hat - Brown Fedora Hat with Dark Brown Band - Adults TV Film Fancy Dress Costume Accessory

The 1 size was not good unless you have a huge head

Nowhere does this product state it’s size but at a party of all adults, it did not fit on a single persons head. Absolutely tiny and stiff as a board. Suitable perhaps for a child but would probably be uncomfortable for them to wear.

This is essentially shaped cardboard. It does not fit well on your head and is easily flattened. Suitable for fancy dress as a one off but don't expect it to last.
