I used 13 when i learned how this all worked...if memory surveys they are the same method. Make a cloth that you need, more patches the smother it looks for me any way, add the SimCloth from change to, plug in, hash, simcloth to a material and apply.
LEAVE A FEW POINTS NOT UNDER THE CLOTH MATERIAL or it will fall away.
Increase air drag to make it affected by a wind force.
You'll get something like this, Ummm...looking back the tutorial shows it better for it has screen shots
