'Attire' in the Bible

On the third day, Esther put on her royal attire and stood in the inner courtyard of the palace in front of the king's quarters. The king was sitting on his royal throne in the throne room, opposite the entrance to the building.

let them bring royal attire which the king himself has worn and a horse on which the king himself has ridden -- one bearing the royal insignia!

Now Mordecai went out from the king's presence in purple and white royal attire, with a large golden crown and a purple linen mantle. The city of Susa shouted with joy.
