A couple of examples I've found:
Metallic Coated Denim Vest at Forever21
Days of Vine and Roses dress at Modcloth
Metallics are practically everywhere. I suggest buying staple pieces like a metallic bomber jacket or something that will last longer than a few months. A pair of skinny metallic jeans might sound cool now, but I don't expect this trend to last too long. Still, it's original and I'm certainly going to spend into it.
