Many Elementals who turn to the darkness will remove their vibrant clothing (the color of their element) and replace it with black. The reason why is unknown, but it is believed it's how these Elementals devote themselves to Nerezza, where nearly 90% of the population wears black.
I find the whole Gianfranco Ferre collection one of the most exciting things I've seen in fashion in a while. wearable, rugged, luxurious, infused with this warrior thing and the way those belts are looped. LOVE it
