Tasteless, fashionable drink Ingrid drained (7)
I believe the answer is:
insipid
'tasteless' is the definition.
(similar in meaning)
'fashionable drink ingrid drained' is the wordplay.
'fashionable' becomes 'in' (in can mean fashionable or trendy).
'drink' becomes 'sip' (sipping is a kind of drinking).
'drained' means to remove the middle letters.
'ingrid' with its middle removed is 'id'.
'in'+'sip'+'id'='INSIPID'
(Other definitions for insipid that I've seen before include "Bland, flavourless" , "Very weak" , "devoid of flavour" , "dry" , "Dull" .)
