Companion’s corset adjusted (6)

I believe the answer is:

escort

'companion's' is the definition.
(escort is a kind of companion)

'corset adjusted' is the wordplay.
'adjusted' indicates an anagram.
'corset' with letters rearranged gives 'ESCORT'.

(Other definitions for escort that I've seen before include "Bodyguard" , "Lead" , "Companion: train" , "One who accompanies, for protection or as an honour" , "'Accompany, perhaps protectively (6)'" .)

I've seen this clue in The Times.
