One's put on something inspirational, or simple garment? (5)
I believe the answer is:
lungi
'simple garment?' is the definition.
(type of southeast Asian garment)
'one's put on something inspirational' is the wordplay.
'one' becomes 'i' (Roman numeral).
'put on' says to put letters next to each other.
'something inspirational' becomes 'lung' (lungs breathe in or inspire).
'i' put after 'lung' is 'LUNGI'.
'or' acts as a link.
(Other definitions for lungi that I've seen before include "Eastern dress" , "simple garment" , "Type of sarong" , "Indian man's loin-cloth" , "worn piece of cloth" .)
