Attracting attention by reason of being unusual (8)
I believe the answer is:
striking
'attracting attention by reason of being unusual' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for striking that I've seen before include "Hitting or refusing to work" , "Conspicuous" , "not working" , "means of putting pressure on employers" , "Conspicuously impressive" .)
