It's a self portrait, and obviously (look at the dogs) Mr. Desportes thought he was quite the Man's Man. He isn't wearing a wig, which says, "I'm having a sporting good time with my viral man's hair" Overall, it's a very cocky, wonderful, self proclamation of wealth and virility. I think both his waistcoat and breeches are velvet, but since i live in Floridee, I will probably modify them to linen. I love this painting, and will make a viable recreation (for my climate) with your alls help! :-)
