Women are dancing the twist (7)
I believe the answer is:
wreathe
'twist' is the definition.
(wreathing is a kind of twisting)
'women are dancing the' is the wordplay.
'women' becomes 'w'.
'dancing' indicates anagramming the letters.
'are' anagrammed gives 'rea'.
'w'+'rea'+'the'='WREATHE'
(Other definitions for wreathe that I've seen before include "Intertwine, curl round" , "Surround, encircle" , "Move in a twisting way" , "wind" , "Twist together" .)
