Hands on hips, elbows out (6)
I believe the answer is:
akimbo
I believe this clue is a double definition.
'hands on hips' is the first definition.
(I've seen this before)
'elbows out' is the second definition.
(I've seen this before)
(Other definitions for akimbo that I've seen before include "Ballet step" , "(Arms) on hips" , "With hands on hips and elbows turned outwards" , "Way of standing" , "With hands on hip, elbows out" .)
