Zeyd cloth

Zeyd cloth was a black-patterned, non glossy fabric that had square waffle styled weaves. The Dark Lord of the Sith Darth Sidious wore monk-like, hooded robes made of zeyd cloth. While some leaders would have donned clothes of the finest synthsilk, Sidious continued to wear his plain Sith robes when he became Galactic Emperor after the end of the Clone Wars.
