Body, trunk (5)
I believe the answer is:
torso
I believe this is a double definition.
'body' is the first definition.
(a person's middle)
'trunk' is the second definition.
(both can mean a person's chest)
(Other definitions for torso that I've seen before include "Body, minus its head and limbs" , "Poorly-dressed child" , "Roots out in trunk of the body" , "unfinished work" , "Body's core" .)
