Monarch cutting high costs for hosiery items (9)

'hosiery items' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe you can see an association between them that I can't see?

'monarch cutting high costs' is the wordplay.
'monarch' becomes 'king' (male monarch).
'cutting' is an insertion indicator (some letters cut their way into a word).
'high' indicates anagramming the letters (can mean drunk or on drugs and hence disordered).
'costs' is an anagram of 'stocs'.
'king' going inside 'stocs' is 'STOCKINGS'.

'for' is the link.
