Choose to be well padded? (5)
I believe the answer is:
plump
This clue is a double definition.
'choose' is the first definition.
(thesaurus)
'well padded?' is the second definition.
(I've seen this in another clue)
'to be' is the link.
(Other definitions for plump that I've seen before include "Having a full rounded shape" , "Chubby, round" , "Well rounded - opt suddenly" , "Chubby, rounded" , "Portly" .)
