Epic Armoury’s Crinkle Undershirt is a loose-fitting, lightweight, crepe cotton shirt. Around the wrist and the neckline are drawstrings that allow you to tie it in or wear it loose as you wish. It is an excellent undergarment for most costumes, as shirts have existed for at least a thousand years. The crepe cotton is slightly transparent, so wearing a different undergarment is advised if used as an overshirt.
