When I was in school I used to wear sports gear ( Fila , Ellesse and Tacinini and Kappa) then got into CP and Stone Island at about 19/20 . Swank in London was a favourite shop of mine
Used to pop over to Bristol for trainers, or Bolwells in Blackwood for the deadstock. Edwards sports in St Johns square used to have the odd pair of Gazelle etc, but that was about it in cardiff.
