Rather special ties in film noted for actor's dress (7)
I believe the answer is:
tootsie
'film noted for actor's dress' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'rather special ties in' is the wordplay.
'rather' becomes 'oot' (I can't justify this - if you can you should believe this answer much more).
'special' indicates anagramming the letters.
'in' means one lot of letters goes inside another.
'ties' is an anagram of 'tsie'.
'oot' inserted into 'tsie' is 'TOOTSIE'.
Can you help me to learn more?
(Other definitions for tootsie that I've seen before include "Foot or toe - I set, too (anag)" , "Film with Dustin Hoffman" , "What's furthest from a child's mind" , "Part of foot" , "Funnily enough, foot" .)
