Prada jeans size TBD?

I bought these in Italy 7 years ago. I cut out the size but I think they are size 38 or 40. I tried them on and they are big in the waist but fit in the glute. They are very long. I am 5’4”. For reference, my current measurements are 36 hip 26 waist. I had to buy them but can’t even wear them. Let’s make these a sisterhood of traveling pants. 💕
