Vintage 70’s? Levi's Orange Tab 575 Blue Bell Bottom High Waist Jeans Mens 32x34.  I am sizing these w/o any size tags so SEE MEASUREMENTS IN PICTURES.  Pre owned, showing wear and distressing, small hole forming above right pocket, on right knee, and at bottom flares (SEE PICTURES).  Overall great condition for age.  There is a 575 on the back of the fly button (SEE PICTURES), but no other interior tags.  in trying to date them it says 70’s-90’s?  Please if you know more about them and want to provide please be kind!  Im trying to learn with little info on the jeans themselves 🙏🏻.  Levi's men’s flared jeans in a washed indigo denim. Subtle whiskering and light fading through the thighs. Slight distressed detail on one knee. Classic five-pocket styling with flared legs for a retro silhouette.
