Bandanna is too much for her (4)
I believe the answer is:
anna
'her' is the definition.
(I've seen this before)
'bandanna is too much' is the wordplay.
'too much' says the answer is hidden in the clue (the clue hides the answer plus unneeded letters).
'ANNA' is hidden in the letters of 'bandanna is'.
'for' is the link.
(Other definitions for anna that I've seen before include "Book by Tolstoy" , "- - Ford (TV)" , "Unit of length" , "Former one sixteenth of Rupee" , "Former Indian coin, girl" .)
