Mock article fitting for Men Only (8)

I believe the answer is:
codpiece
'fitting for men only' is the definition.
I can't judge whether this definition defines the answer.
'mock article' is the wordplay.
'mock' becomes 'cod' (cod can mean false or inauthentic).
'article' becomes 'piece' (article can mean a thing or item).
'cod'+'piece'='CODPIECE'
Can you help me to learn more?
(Other definitions for codpiece that I've seen before include "for promotion of virility?" , "Medieval male accoutrement for the nether regions" , "Male dress item of former times" , "What kept privates in place" , "men put on centuries ago" .)
