Dress to admire when given new hem (5)
I believe the answer is:
adorn
'dress' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for adorn that I've seen before include "Deck" , "Attire" , "dress" , "Make more attractive" , "Bedeck" .)
