Lili Crepon Stretch Dress Riding Pants

I got a large one person's collection that I will be listing. Most of the pieces were bought in France so the sizing tags are in EU sizes, I will list them as the supposed US sizes. Many are black so difficult to get good pictures of them (we are working on stuff to help). There is a bit of smell from them from storage, nothing real bad. This is a pair of pants by Lili Crepon. They have what feels like leather at the inside of the knees so I am thinking they were horse riding pants. They are super stretchy. It is marked as size T38 (US 6) and inseam is about 26 inches long and 13 inches wide at the waist flat. I am seeing some broken threads at the outer seam of the left leg but it seems still very secure.
