Refuse to hug model for body (7)

Ross

I believe the answer is:

density

'for body' is the definition.
(density is a kind of body)

'refuse to hug model' is the wordplay.
'refuse' becomes 'deny' (synonyms).
'to hug' means one lot of letters goes inside another.
'model' becomes 'sit' (e.g. for a painting).
'deny' going around 'sit' is 'DENSITY'.

(Other definitions for density that I've seen before include "Closeness" , "Concentration, compactness" , "can be relative" , "showing obtuseness" , "The compactness of a substance" .)

I've seen this clue in The Telegraph.
