In an interesting article — https://fashionista.com/2018/10/sustainable-ethical-fashion-clothes-aesthetic-style — Dominique Drakeford explains that African slaves were required to wear drab clothing. However, for liturgies and veneration, they had license to make their own clothes and so favoured cloth of vibrant constellations of colour. She writes:
“In order to feel liberated and to make a distinction between their working body and worshiping body, enslaved seamstresses used their earnings to buy bright fabrics to make colorful church garments that differed from their laboring clothes.”
An excellent example of veneration and refinement.
