Mucros 8 Piece Gray Herringbone Driving Cap - Skellig Gift Store - grey - XXL

How can I restore shape? Probably due to being shipped in a bag not a box, it’s misshaped.

my hat size is 7.5. what size do you recommend?

How true to the color are these caps specifically the Charcoal Herringbone is it really charcoal because the picture looks bluish?
