Size 18 NWT Womens Matilda Jane Good Hart Somerset Skinny Jean - Black.  Also please note from photos there are some pre designed holes in the knees.

This pair of jeans were from a sample sale.  Brand new never washed.  But they were tried on by me, and a tad big for me.  I usually wear a size 18 from Old Navy and Gap.  Definitely some stretch in these.
