Shorts pound, shocking her donees (10)
I believe the answer is:
lederhosen
'shorts' is the definition.
'pound shocking her donees' is the wordplay.
'pound' becomes 'l'.
'shocking' indicates an anagram (I've seen this in other clues).
'her'+'donees'='herdonees'
'herdonees' is an anagram of 'ederhosen'.
'l'+'ederhosen'='LEDERHOSEN'
(Other definitions for lederhosen that I've seen before include "Bavarian leather shorts" , "Alpine shorts" , "trousers displayed" , "Clothing" , "Bavarian shorts with braces" .)
