NEW with tags "Rustuc Denim" Jeans "size 18" but measurements as a size 12

they SAY size 18? added the exact measurements cuz 🤔 fishy mystery tag glued on top of stitched in label? These jeans are a crazy mystery but all I know is they are brand new and these are the measurements. Fishy......so priced accordingly Inseam 30 Length 38 Waist 15/30 all measurements taken laying flat. (so 30x30 which corresponds to a US 12 or Eu40)
