Beholds an unusually fair lady (3,6)
I believe the answer is:
ash blonde
'fair lady' is the definition.
(woman with ash blonde hair)
'beholds an unusually' is the wordplay.
'unusually' indicates an anagram.
'beholds'+'an'='beholdsan'
'beholdsan' with letters rearranged gives 'ASH-BLONDE'.
(Other definitions for ash blonde that I've seen before include "fair hair" , "Description of shock" , "lady with light hair" , "Hair colouring" , "silver-haired type" .)
