Reckon Hoskins is a G wearing piece from Evisu (7)
I believe the answer is:
imagine
'reckon' is the definition.
(I know that reckon can be written as imagine)
'hoskins is a g wearing piece from evisu' is the wordplay.
I cannot really see how this works, but
'hoskins' could be 'i' (where the crossword setter is 'Hoskins') and 'i' is found in the answer.
'a' is present in the answer.
'g' could be 'm' (synonyms) and 'm' is found in the answer.
'wearing' could be 'in' (in certain clothing) and 'in' is located in the answer.
The remaining letters 'ge' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for imagine that I've seen before include "Assume" , "Suspect" , "1971 John Lennon song" , "Conceive in the mind" , "Picture in mind, envisage" .)
