Fearless virgin, say, having fun after shedding top (9)
I believe the answer is:
undaunted
'fearless' is the definition.
(similar in meaning)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for undaunted that I've seen before include "Intrepid" , "Not afraid or discouraged" , "showing no fear" , "Fearless" .)
