Bare or nude, and dancing (9)
I believe the answer is:
unadorned
'bare' is the definition.
(thesaurus)
'or nude and dancing' is the wordplay.
'dancing' indicates anagramming the letters.
'or'+'nude'+'and'='ornudeand'
'ornudeand' with letters rearranged gives 'UNADORNED'.
(Other definitions for unadorned that I've seen before include "Not decorated, plain and simple" , "Simple and plain as around den" , "Without embellishment" , "Plain, undecorated" .)
