Criticise one wearing those leggings (9)

I believe the answer is:

pantihose

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

'criticise one wearing those leggings' is the definition.
I can't tell whether this definition defines the answer.

'criticise one wearing those' is the wordplay.
'criticise' becomes 'pan' (informal term meaning to criticise heavily).
'one' becomes 'i' (Roman numeral).
'wearing' is an insertion indicator.
'i' put inside 'those' is 'tihose'.
'pan'+'tihose'='PANTIHOSE'

Can you help me to learn more?

(Other definitions for pantihose that I've seen before include "Tights" , "In teashop (anag.)" , "garments?" , "underwear" .)

I've seen this clue in the Sydney Morning Herald.
