{"type":"firestarter.listing","listing":{"id":"lst_sRRVdlDc","product_name":"Big Oxford Shirt ~ White","category":"Tops","description":"The Big Oxford is a modern, casual take on the traditional oxford. The shirt is cut with a wide chest and shoulders, coupled with looser sleeves. The generous proportions are matched with a carefully considered body and sleeve length so the shirt maintains its oversized feeling without appearing too big. The shirt has been garment washed for a perfectly broken-in hand.
