Credit on tax to obtain a dress accessory (6)
I believe the answer is:
cravat
'dress accessory' is the definition.
'cravat' can be an answer for 'accessory' (I've seen this before). I'm not certain of the 'dress' bit.
'credit on tax to obtain a' is the wordplay.
'credit' becomes 'cr'.
'on' means one lot of letters go next to another.
'tax' becomes 'vat' (British sales tax).
'to obtain' is an insertion indicator.
'cr'+'vat'='crvat'
'crvat' placed around 'a' is 'CRAVAT'.
Can you help me to learn more?
(Other definitions for cravat that I've seen before include "Cloth for the neck" , "Scarf worn instead of tie" , "leisure-wear" , "Type of neckwear" , "Male neckwear" .)
