No elders he dressed in shorts (10)
I believe the answer is:
lederhosen
'shorts' is the definition.
'no elders he dressed' is the wordplay.
'dressed' is an anagram indicator ('dress' can mean 'prepare').
'no'+'elders'+'he'='noeldershe'
'noeldershe' anagrammed gives 'LEDERHOSEN'.
'in' is the link.
(Other definitions for lederhosen that I've seen before include "Short leather trousers with braces" , "Bavarian shorts with braces" , "Clothing" , "Alpine shorts" , "pants" .)
