Adventurous dancing in drag (6)
I believe the answer is:
daring
'adventurous' is the definition.
(similar in meaning)
'dancing in drag' is the wordplay.
'dancing' is an anagram indicator.
'in'+'drag'='indrag'
'indrag' anagrammed gives 'DARING'.
(Other definitions for daring that I've seen before include "Bold and reckless" , "Derring-do" , "Challenging or defying" , "rash" , "A grind (anag.)" .)
