Vintage Pants from the 1970s by Sears

Here is an amazing pair of vintage pants from the 1970s by Sears. Not sure about the fabric. Almost has a denim feel, but also kinda polyester-y. Not sure what to call the color either. Light red? Dark pink? It ALMOST has a shark skin vibe. Guess I'll go with light red, with pink stitching throughout. Two button and zipper front. A pocket on each hip, with a buttoned pocket right beneath it. Two buttoned pockets on the back. Pretty substantial flare to the bottom of the legs. These are sleek, stylish, and cool. They are medium weight. They are in excellent condition with years of life left! The tag says 32-29, but here are the measurements taken laying flat:

Waist: 16" 

Width of one leg (mid thigh) 10"

Length:  39"
