Outfit held centre star (5)
I believe the answer is:
rigel
'star' is the definition.
(star in the constellation Orion)
'outfit held centre' is the wordplay.
'outfit' becomes 'rig' (rigging is a kind of outfiting).
'centre' indicates the central letters.
The central letters of 'held' are 'el'.
'rig'+'el'='RIGEL'
(Other definitions for rigel that I've seen before include "shiner" , "Orion's brightest star" , "Brightest star in Orion" .)
