I ordered this in cobalt blue and it is a beautiful deep shade, slightly toward purple. The fabric is a nice  lightweight but not insubstantial fabric, definitely not gauzy. If you want gauzy for summer, this isn't it. The description here says polyester but the tag on mine says 100% cotton. From the feel, I am inclined to think it is a synthetic. No snags or holes and it doesn't feel as if it will snag easily. I'm going to order another.
