Here are the answers to the elf armor questions from Jen Running Deer...

The cloth that shows under the armored skirt seemed to
be a rusty, coppery red metallic with a slightly
iridescent sheen to it. The fabric sleeves, though,
are sort of a snakeskin/fishskin look, with browns and
maroons, again with an iridescent sheen and black
outlining the "scales".

The cloak was a grey brown tone.
