Showy things worn for the better part of a year (6)
I believe the answer is:
finery
'showy things' is the definition.
(I've seen this in another clue)
'better part of a year' is the wordplay.
'better' becomes 'finer' (I've seen this in another clue).
'part of' suggests taking the first letters (I've seen 'part' mean this).
The initial letter of 'year' is 'y'.
'finer'+'y'='FINERY'
'worn for the' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for finery that I've seen before include "Glad rags, best duds" , "Ostentatious decoration" , "Elaborate clothes and accessories" , "Showy clothing" , "Elaborate clothing, jewellery etc" .)
