Okay so hats and shoes fit everybody different. I like this hat a lot. The material is not real thin and I like the look. Regarding the fit, my mellon measures 23 1/2 and the XL fit perfect. But know this, if you have thick hair or measure more than 23 1/2 the XL will likely not be big enough. Were there some wrinkles?  Yup. But not too bad and they don't bother me a bit. I also have a Bailey where the XL fits just a little better but that was $85. Totally pleased with this deal plus Im having a little graphic design embroidered in the front of it
