John 19-21

It took about 20 minutes to read these last chapters of John's Gospel. In 19:23 John noted that the four soldiers who crucified Jesus divided his clothing between them. Jesus' undergarment was the 5th item. I wonder what the other four pieces were? His sandles would have been one piece (what good is one sandle?), his garment(robe) would have been number two. He could have been wearing a heavy cloak (it would have been cool in the garden the night before). But what would be the fourth item; Prayer shaw? A belt?
