Guided son here, wearing foreign attire (10)
I believe the answer is:
lederhosen
'foreign attire' is the definition.
Although both the answer and 'attire' are nouns, they are not in the same form of the noun.
'guided son here wearing' is the wordplay.
'guided' becomes 'led' ('lead' can be a synonym of 'guide').
'wearing' indicates anagramming the letters (wear can mean to become damaged).
'son'+'here'='sonhere'
'sonhere' with letters rearranged gives 'erhosen'.
'led'+'erhosen'='LEDERHOSEN'
Can you help me to learn more?
(Other definitions for lederhosen that I've seen before include "Short leather trousers with braces" , "German outfit" , "trousers displayed" , "Bavarian shorts with braces" , "Clothing" .)
