Being fashionable makes Ken scared! (4)
I believe the answer is:
chic
'being fashionable' is the definition.
(chic means stylish or fashionable)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for chic that I've seen before include "Fashionably elegant" , "Fashionable good taste" , "Stylish and elegant - in France" , "Well turned out" , "French elegance" .)
