Being neither into football nor rucking, I can’t ever claim to have been a casual. Having said that they’ve championed some class clothing along the way, such as the Adidas SL80s and CP Company’s Mille Miglia Coat. The shop on 80s Casuals celebrates some of these items with some well designed looking tees and sweats.
Incidentally, if you’re interested in the history of this oft-overlooked youth cult, try Phil Thornton’s Casuals, a well-written book which pays a decent amount attention to the clothes and less to vicarious tales of which “firms” the author has had. Available from the same site or Amazon.
