One of the things I've noticed with Indy hats is that the shape of your head versus the block of the hat has a lot to do with how "Indy" the hat really looks on you. Especially if you're looking at a SoC or Raiders hat, the way your head fits and pushes against the hat will affect brim curl and various other characteristics of the hat. I have several (non Indy) hats which develop brim swoop, etc. simply because of how tight the hat is and how the opening is shaped.
Case in point, I think Holt and I share the same hat size, but I could never get my FedIV to look the same as his on my head, even after he told me how he shaped his hat. I think this has a lot to do with having a different head shape. On the flip side, my AB CS looks really good on me because of how that hat is shaped to my head.
If I have a long oval head and put on a round oval hat, the shape of my head will push the front and back of the hat, adding to the front profile stovepipe effect while giving the brim a bit more swoop. However, I have no clue what my head shape really is. So before this thread goes down a different path based on the above, can anyone answer me on how to find out your headshape? Discuss.
