Seamstress listens to Swift on the radio? (6)
I believe the answer is:
tailor
'seamstress' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tailor that I've seen before include "Couturier" , "Seamster" , "Fashion" , "Rialto (anag) -- adjust to a specific need" , "Involving grief, death, destruction" .)
