For example, wife wearing king's stockings? (7)

I believe the answer is:

legwear

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

'stockings?' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'for example wife wearing king's' is the wordplay.
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'wife' becomes 'w' (abbreviation).
'wearing' is an insertion indicator.
'king' becomes 'lear' (Shakespeare's King Lear).
'eg'+'w'='egw'
'egw' put inside 'lear' is 'LEGWEAR'.

Can you help me to learn more?

(Other definitions for legwear that I've seen before include "Stockings etc" , "Eg, socks, stockings" .)

I've seen this clue in The Times.
