3D representation of female with half-ripped pants (6,3)
I believe the answer is:
relief map
'3d representation' is the definition.
'female with half-ripped pants' is the wordplay.
'with' is a charade indicator (letters next to each other).
'half' indicates taking half.
'pants' indicates anagramming the letters (UK informal term for 'nonsense' or 'rubbish').
'ripped' cut in half is 'rip'.
'female' after 'rip' is 'ripfemale'.
'ripfemale' with letters rearranged gives 'RELIEF MAP'.
'of' acts as a link.
(Other definitions for relief map that I've seen before include "Street plan" , "possibly colourful plot" , "Plan with contours" , "shady plan" , "I exhibit ups and downs" .)
