Fair bishop left order done (6)
I believe the answer is:
blonde
'fair' is the definition.
('blonde' can be similar in meaning to 'fair')
'bishop left order done' is the wordplay.
'bishop' becomes 'b' (abbreviation used in chess).
'left' becomes 'l' (common abbreviation).
'order' indicates anagramming the letters.
'done' with letters rearranged gives 'onde'.
'b'+'l'+'onde'='BLONDE'
(Other definitions for blonde that I've seen before include "What may follow Strawberry" , "Fair lady" , "Light-haired woman" , "Kind of girl that gentlemen are said to prefer" , "Of a woman, having fair hair (6)" .)
