Get into gear? (5)
I believe the answer is:
dress
This clue is a double definition.
'get' is the first definition.
(thesaurus)
'gear?' is the second definition.
(I've seen this before)
'into' is the link.
(Other definitions for dress that I've seen before include "One-piece garment" , "get into gear" , "Do some cover work in theatre" , "Clothing - groom" , "clean > bandage" .)
