1980's Silver Jogger Pants by Bill Tornade made in France.
These awesome, silver lame joggers were once used for a photo shoot in Beverly Hills in the 80s and promptly put into storage until we found them. 
They are pull-up style, super lightweight, and comfy. The waist is only slightly elastic and, by design, needs a belt. We love the Iconic Paloma Picasso OXO belt for sale in our Accessories Collection. Features fabric tie straps at the ankles for an open or cinched cuff, a pleated front, side pockets, and belt loops. 
Waist 34", hips 42", length 42". 
The modern size is M/L and the condition is Excellent. Model is 5'11".

This item is sold from an excellent, highly rated vintage boutique.
