Contribution from fashionable place (5)
I believe the answer is:
input
'contribution' is the definition.
(input means someone's contribution to something)
'fashionable place' is the wordplay.
'fashionable' becomes 'in' (in can mean fashionable or trendy).
'place' becomes 'put' (synonyms).
'in'+'put'='INPUT'
'from' acts as a link.
(Other definitions for input that I've seen before include "Data etc supplied to computer" , "Contribution of work or information" , "contributed information" , "Data contributed" , "Signal entering a circuit" .)
