Do without alcohol? (3,5)
I believe the answer is:
tea party
'do without alcohol?' is the definition.
(party or 'do' with non-alcoholic drinks)
This is the entire clue.
(Other definitions for tea party that I've seen before include "sort of celebration" , "afternoon get-together" , "Staunch patriots" , "Social gathering (for Bostonians?)" , "US political movement" .)
