This is a screenused costume worn by Autolycus played by Bruce Campbell and stunt double, Ben Cooke. Autolycus worn different costumes during the XWP and HTLJ series, this belongs to the last outfit seen in both tv shows and in my opinion, the more elaborated and detailed one.
This costume has 6 pieces: the iconic green suede vest, the black fabric skirt with a detailed flower trim, the leather pants also used by Ares and other male characters, black leather boots, ornated gauntlets, my favourite piece, and green suede belt.
The Hero costumes used to be labeled with the name of the main actor and sometimes also the character name, this is the case. Also, in the case of the green suede vest I believe that after been used by Bruce Campbell during a few episodes, they left this vest for the stunt actor, Ben Cooke. In the trouser is written: “Autolycus Stunt Double” and in the boots also.
