It was customary for the soldiers on duty at a crucifixion to divide the clothing and personal possessions of the prisoner among themselves. We would look at it today as a fringe benefit of the job. The Jews generally wore 6 articles of clothing: a loin cloth, which they apparently let Jesus wear to the grave, a pair of sandals, a head covering, a belt, a robe, and a tunic.

Matthew 27:54  When the centurion and those with him who were guarding Jesus saw the earthquake and all that had happened, they were terrified, and exclaimed, “Surely he was the Son of God!”
