Bra recycled into little lad's garment (6)
I believe the answer is:
tabard
'lad's garment' is the definition.
'tabard' can be an answer for 'garment' (tabard is a kind of garment). I am unsure of the 'lad's' bit.
'bra recycled into little' is the wordplay.
'recycled' indicates anagramming the letters.
'into' is an insertion indicator.
'little' becomes 'tad'.
'bra' with letters rearranged gives 'bar'.
'bar' inserted within 'tad' is 'TABARD'.
Can you help me to learn more?
(Other definitions for tabard that I've seen before include "Knight's outer tunic" , "Herald's jacket" , "Gilet" , "Clobber" , "Short sleeveless tunic" .)
