Pants for drinks (6)
I believe the answer is:
shorts
This clue is a double definition.
'pants' is the first definition.
(shorts is a kind of pants)
'drinks' is the second definition.
'for' is the link.
(Other definitions for shorts that I've seen before include "Boxers" , "Garment" , "Trousers that end at or above the knee" , "Reduced trousers" , "bottom gear" .)
