Dress carried back to end of queue (6)
I believe the answer is:
enrobe
'dress' is the definition.
(I've seen this before)
'carried back to end of queue' is the wordplay.
'carried' becomes 'borne' (past tense of 'bear' in the sense of 'carry').
'back' is a reversal indicator.
'to end of' suggests the final letters.
The last letter of 'queue' is 'e'.
'borne' backwards is 'enrob'.
'enrob'+'e'='ENROBE'
(Other definitions for enrobe that I've seen before include "make investment?" , "put on formally ..." , "Fancy" , "Dress, put on vestments" , "put on gown" .)
