Tosh. I wear ‘socks’ whether I’m dressed ‘formally’ or not. Dinner jacket/suit, work suit, ripped jeans, smart chinos, workman’s trousers, shorts, you name it - on my feet in all cases are just ‘socks’. And these highly patterned ‘socks’ are just plain ordinary common or garden socks. Formal socks, my arse. This is just marketing wankers’ rhetoric to ‘dress’ up a perfectly standard item of everyday wear.
