Something lyrical about a redhead's garment (6)
I believe the answer is:
sarong
'garment' is the definition.
(sarong is a kind of garment)
'something lyrical about a redhead's' is the wordplay.
'something lyrical' becomes 'song' (I am not sure about this - if you are sure you should believe this answer much more).
'about' is an insertion indicator.
'redhead' becomes 'r' (head letter of 'red').
'a'+'r'='ar'
'song' placed around 'ar' is 'SARONG'.
Can you help me to learn more?
(Other definitions for sarong that I've seen before include "Asian skirt-like garment" , "Malay skirt-like garment" , "Brightly-coloured skirt in the South Pacific" , "Draped garment" , "Unisex Malayan garment of cloth wrapped around body" .)
