Palindromic fashion magazine (4)
I believe the answer is:
elle
'palindromic fashion magazine' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for elle that I've seen before include "World's best-selling fashion magazine" , "Ms MacPherson, supermodel" , "French word for 'she'" , "Fashion magazine - the French "She"" , "Is she in France" .)
