Clothing and drink reportedly coming from south-east Asia?
I believe the answer is:
necktie
'clothing' is the definition.
(necktie is a kind of clothing)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for necktie that I've seen before include "Item worn round collar (mainly US)" , "Strip of fabric often worn by men" , "American garment" , "Fashion accessory - cite Ken (anag)" , "Ascot?" .)
