These places usually have various types of movie and TV props for sale, including English big-brimmed hats.

Alternatively, you can consider attending art exhibitions, auctions or second-hand markets. Sometimes, you may find rare movie and television props in these places.

Either way, it's recommended that you double-check the item description and images before making a purchase, and ask the seller any questions to make sure you're getting the item you want.
