Vintage high waisted jeans, small

This is a very chic high waisted jeans from United Colors of Benetton. It says size 40 but its actually size 24 given the design. It’s vintage, so the sizing is different from the modern pants. Non-stretch, 100% cotton: Please refer to the pictures of measurements laying flat which is the actual size.I don’t want to let it go as this is one of the most stylish jeans I ever wore and I got a lot of compliments but 2 years after giving birth, I don’t think I will be able to go back to my old size 😔. The right color is the one with the brown background. Still in very good condition. Measurements laying flat: Waist - 12.5” (will fit a size 24” waist to be safe) Hips- 16.5” Rise- 11.5” Inseam- 24” Total lenght, from waist to hem - 36”
