Grab outlandish attire (4)
I believe the answer is:
garb
'attire' is the definition.
(both can mean clothing)
'grab outlandish' is the wordplay.
'outlandish' is an anagram indicator.
'grab' with letters rearranged gives 'GARB'.
(Other definitions for garb that I've seen before include "Distinctive dress of a group" , "Dress - habit" , "something to wear" , "Kit" , "Raiment" .)
