Vintage Long Sleeve Western Snap Dress by Lee

This is a wonderful long sleeve dress from the 70s/80s by Lee. My guess would be 100% cotton and made in the USA. Dark denim fabric with yellow stitching. Eleven button front, two on each cuff, a buttoned pocket on each breast, a six inch slit up each side, and a hidden pocket on each hip. It has a belt that I doubt is original, but it came with it, so it's leaving with it. Medium weight, soft and comfy. It's in amazing condition with years of life left! Here are the exact measurements taken laying flat (be sure to reference the last photo to see how I measure dresses)
