With Asian dress cut short, eat fish (7)
I believe the answer is:
sardine
'fish' is the definition.
(sardine is a type of fish)
'with asian dress cut short eat' is the wordplay.
'with' means one lot of letters go next to another.
'asian dress' becomes 'sari' (I've seen this before).
'cut short' means to remove the last letter.
'eat' becomes 'dine' (to dine is to eat a meal).
'sari' with its last letter taken off is 'sar'.
'sar'+'dine' is 'SARDINE'.
(Other definitions for sardine that I've seen before include "Fish (often tinned)" , "FRENCH FISH" , "Stonefish OR? Stone" , "Small fish, usually canned" , "Fish in tin?" .)
