vtg blue denim skort

Vintage blue denim skort. No pockets, but that makes them more comfortable and more slimming. Beautiful two tone button with a sun on it! The main tag was removed years ago for comfort, but the remaining nub has a number on it, something like 51 85 251 5 . Definitely has some cotton, not sure if it's 100% cotton. About 2 inches smaller in the entire waist circumference than the size 10 denim shorts in my closet. Other than missing tag and minor wear, very good condition!
