If we are talking about how you look while skiing, not what you are wearing; then ability and style are linked. When you are learning to ski, most of what you are learning is how to look good skiing. Someone who is a good skier is going to look good in the air or in their turns, someone who is bad wont.
When I feel out of control in the air or something and start waving my arms around I think it looks terrible, but then I watch video of it and my arms are hardly moving. Thats because people who are good skiers have been training themselves all along to have a quiet body, which is the most important part of having good style.
