Incredible Vintage 70’s Denim Dress

Amazing denim dress from the 70’s with killer oversized collar and buttons. Absolutely fabulous condition except for its lost its very bottom button. I imagine it wouldn’t be to difficult to make one with fabric from underneath the dress. It’s very sturdy almost like couture and has a very distinctive look. Pretty obsessed with this one. Fits like an medium/large but please see photos for exact measurements.
