Away, in good health, getting set of clothes (6)
I believe the answer is:
outfit
'set of clothes' is the definition.
(I've seen this before)
'away in good health getting' is the wordplay.
'away' becomes 'out' ('out' can be a synonym of 'away').
'in good health' becomes 'fit' (I've seen this before).
'getting' says to put letters next to each other.
'out'+'fit'='OUTFIT'
(Other definitions for outfit that I've seen before include "Team" , "Cohesive unit, eg a military company" , "what to wear?" , "Organistion or set of clothing" , "Set of matching clothes" .)
