Fundraiser gets rash from feathers
I believe the answer is:
fete
'fundraiser' is the definition.
(I have seen 'Outdoor fundraiser' mean 'fete' so perhaps 'fundraiser' could also mean 'fete')
'rash from feathers' is the wordplay.
'from' is a deletion indicator.
'feathers' with 'rash' taken away is 'FETE'.
'gets' is the link.
(Other definitions for fete that I've seen before include "Organised outdoor party or charitable event" , "Outdoor bazaar for charity" , "A festival of feet" , "Outdoor festivity" , "Entertain regally" .)
