MAZCrushable Hand Made Fedora Trilby Hat with Leather Type Band 100% Wool

Is this hat delivered flat

Does teal colour hat come in 57cm, i am confused why it only has médium large or small as an option? Are they the same quality as the other colours?

How can you clean it? I am asking because I would like to buy a white one.

I have this hat size 57 in lepoard and i love it. I wanted to know if teal is the same make because it says you dont have it in size 57? But in M?
