Impact wig in Creamy Glow by Natural Image.  Lovely tousled style that can be styled in many ways.  Photography shows the wig to be lighter in color than it is.  I would put it in the medium blonde category with an hint of auburn.  I have photographed it, mainly outside in full sunlight and one photo taken inside to give a better idea of the color.  Problem is, as usual, that different monitors interpret color differently.  To get a better idea of color, you may like to check around the websites showing this wig for color comparisons.

There are two of these for sale - identical.  I liked the look a lot, but decided that the Marilyn look was not quite right for me and went "classical.".
