Close to tears, top fashion designer upset (7)
I believe the answer is:
shatter
'upset' is the definition.
(thesaurus)
'close to tears top fashion designer' is the wordplay.
I cannot quite understand how this works, but
'top' could be 'hat' (I've seen this in other clues) and 'hat' is located in the answer.
The remaining letters 'ster' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for shatter that I've seen before include "Completely upset" , "Go to pieces" , "Smash to pieces" , "Crack" , "Break the minister into little pieces" .)
