Drunk or sober, male wears satisfactory hats (9)

I believe the answer is:

sombreros

I'm a little stuck... Click here to teach me more about this clue!

'satisfactory hats' is the definition.
'sombreros' can be an answer for 'hats' (sombrero is a kind of hat). I am not sure about the 'satisfactory' bit.

'drunk or sober male wears' is the wordplay.
'drunk' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'male' becomes 'm' (common abbreviation).
'wears' indicates an anagram (I've seen 'worn' mean this (worn can mean damaged)).
'or'+'sober'+'m'='orsoberm'
'orsoberm' anagrammed gives 'ombreros'.
's'+'ombreros'='SOMBREROS'

Can you help me to learn more?

(Another definition for sombreros that I've seen is " Mexican hats".)

I've seen this clue in The Independent.
