Thank Christ! I really thought they were a navy addidas three stripe for a sec!
I used to have a pair I made myself a bit like that!... I basically made my own skater style jean... (they were f**king expensive in my day and not readily available)... by cutting the side seam of a normal pair of jeans and adding a strip pf purple heavy weight cotton and then running a strip of silver-grey sequins on top of that... very girly.. but everyone wanted a pair!
