I say casual you say suit
Suit is off eBay. The seller says it's a 1950s swedish army workwear suit. I feel it might be a prison uniform. No tags on it anywhere just 48 (the size) stenciled onto the jacket. I threw it in the wash to get rid of the weird smell and gave it a bit of an iron. Need to double iron these trousers I think though.
Very pleased with the fabric, a sort of sun faded green denim? It's a bit iridescent, tried to get a detail shot after the cut. Trousers have pleats, brace buttons. The only issue with it is all the buttons are super cheap and nasty plastic. Contemplating replacing them. It only cost about #20 all in so if you still don't have a suit for the CASUAL SUIT CHALLENGE why not take a punt. http://www.ebay.co.uk/itm/231327000280? ... EBIDX%3AIT
I got the size 48 and it fits alright. I wouldn't try and size down it'll end in tears.
