<human>: What's the difference between a sombrero and a hat?
<bot>: A sombrero is a traditional Mexican headdress worn by men, typically made of woven straw. It consists of two parts: a crown and a brim. The crown is usually wider than the brim, and the brim is often decorated with colorful ribbons or feathers. A hat, on the other hand, is an item of headwear that covers most of the head and face. It can be made of many different materials, including felt, straw, fabric, plastic, and even paper.
