Tau robe
From Wikipedia, the free encyclopedia

A tau robe is a very simple black or white gown cut to resemble the Greek letter, "tau," or "T".[1]
The arms are usually from fingertip to fingertip, and the bottom hem is usually floor length, as with a ceremonial tabard.[2] Both the arms and body of the gown will flare so that the sleeves being bell sleeves, are wider at the fingers than at the shoulder, and the bottom wider than at the chest. This loose fitting helps with maneuverability while wearing the robe.[3]
