Partners in tight corsets (7)
I believe the answer is:
escorts
'partners' is the definition.
The answer and definition can be both people as well as being plural nouns.
Maybe there's an association between them I don't understand?
'tight corsets' is the wordplay.
'tight' indicates an anagram (tight can mean drunk).
'corsets' anagrammed gives 'ESCORTS'.
'in' is the link.
Can you help me to learn more?
(Other definitions for escorts that I've seen before include "They accompany others" , "Accompanies, perhaps socially" , "Accompanies to protect" , "Armed guards" , "Attendants" .)
