'Tunic' in the Bible

When the soldiers crucified Jesus, they took His clothes and divided them into four parts, a part for each soldier. They also took the tunic, which was seamless, woven in one piece from the top.

Then that disciple (John) whom Jesus loved (esteemed) said to Peter, “It is the Lord!” So when Simon Peter heard that it was the Lord, he put on his outer tunic (for he was stripped for work) and threw himself into the sea [and swam ashore].
