OK, by the light of day,  I took the  large image into Photoshop, and I do
see the line in the fabric when I  blow the shot up  to   where her elbows
are at the bottom of my 17 inch monitor, and the pendant is in the top
quarter.

Then, I adjust the black and white levels to where they should be for her
face, and  the line is gone.

It is a curious  thing to be sure, but  either in Lightroom or  Photoshop, I
adjust the color balance and make the blacks black and white white, I get
rid of the line.

I was looking at the exif for the shot, and I note  it was shot at  160 ISO
and   a 1/125th  of a second.  My best hunch is that the artifact is from
underexposure.
