Outline Klee's absurdly fashionable style (8)
I believe the answer is:
skeleton
'outline' is the definition.
(I've seen this before)
'klee's absurdly fashionable style' is the wordplay.
'absurdly' indicates anagramming the letters.
'fashionable style' becomes 'ton' (ton can mean fashionable style in French).
'klees' is an anagram of 'skele'.
'skele'+'ton'='SKELETON'
(Other definitions for skeleton that I've seen before include "Bone structure" , "Framework (kept in the cupboard?)" , "Minimum number required to keep things ticking over" , "Framework of the body" , "Internal framework" .)
