Charleston dancer (7)
I believe the answer is:
flapper
'charleston dancer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for flapper that I've seen before include "Unconventional young woman in the 1920s" , "one inclined to panic" , "Unconventional nineteen twenties girl" , "fashionable female in twenties" , "She was a flighty young thing" .)
