Rick Owens makes this one. A Google image search will show you his designs. I don't see where he sells his patterns, though. He has some very unique clothing. This one is a bias cut shirt. The bias is what gives it the drapey look. Takes more fabric to make, and is best with the 60" wide fabrics. Depending on how large you are.
Rayons and other 100% poly blends work good. No cotton. It just does not have the "shift" that you need.
Here is something similar that maybe you can adapt.
Hope I have helped.
