'headwear' is the definition.
I can't tell whether this definition defines the answer.

'iron character' is the wordplay.

'fe'+'z'='FEZ'

'of' acts as a link.

Can you help me to learn more?

(Other definitions for fez that I've seen before include "Middle Eastern headgear" , "Tasselled hat" , "Egyptian tasseled hat" , "Egyptian felt cap" , "Turkish tasselled cap" .)
