Desire shown in ripped t-shirt (6)
I believe the answer is:
thirst
'desire' is the definition.
(thirsting is a kind of desiring)
'ripped t-shirt' is the wordplay.
'ripped' is an anagram indicator (I've seen this in other clues).
't'+'shirt'='tshirt'
'tshirt' anagrammed gives 'THIRST'.
'shown in' acts as a link.
(Other definitions for thirst that I've seen before include "Drink to slake it" , "Strong need for drink" , "Dryness" , "A need (for liquid)" , "Physiological need to drink" .)
