Back in the day the typical western hat was bought open crowned and it was up to the owner to shape. Generally that was done over time with use. The open, unmolested, crown a sign of a new or special hat the owner was trying to take care of. In the middle of the 1800s the typical man didn't have a size 7.5 or 8 hat size and a 4" crown was plenty. These days men's heads are bigger and hat crowns are as well. Helps to have a big enough crown to stick your over size melon in. A open crown can help there. Always thought Dan Bocker looked like a goof. Will Brennen not at all. Same for TLJ Had a woman tell me she sold, "hats like that" when she worked in a Wester store but "they would actually hand crease them for you". I wear open crown hats because I like them and they fit my head better. The stay un-creased and unshaped for a reason. How about you?
