VINTAGE rare miller plaid tartan boot cut pants 2

Super rare true vintage boot bottoms western wear pants by Miller. Super retro 70’s style, but I believe this piece dates from waaay before (50’s 60’s) Blue and yellow plaid pattern. Bootcut lightly flared leg. Super high waist and a nice amount of stretch added to it. No size tag but I would say best fits a modern size 2/4. but please refer to measurements. (For me it fits too small) Waist: 13” Hips : 17” Rise 10 1/2” Inseam: 31 1/2” Lm44
