Summary treatment of summery clothing with split around top of hem (5,6)
I believe the answer is:
short shrift
'summary treatment' is the definition.
(synonyms)
'summery clothing with split around top of hem' is the wordplay.
I cannot quite see how this works, but
'clothing' could be 'shorts' (shorts is a kind of clothing) and 'shorts' is present in the answer.
'split' could be 'rift' (I've seen this in other clues) and 'rift' is present in the answer.
A single letter 'h' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for short shrift that I've seen before include "Curt treatment" , "Summary treatment of a matter" , "Brief and unsympathetic treatment" .)
