PEPLUM recycling: SON OF SPARTACUS tunic

Steve Reeve's unique tunic in SON OF SPARTACUS was reused in SEVEN REBEL GLADIATORS; Jeff Cameron is wearing it (Pietro Torrisi is crouching next to him).

I find this odd because I believe Steve's tunic in SON OF SPARTACUS to be almost iconic and seeing worn by another acting in another movie is not quite right.
