Sometimes you can neglect the bare essentials. With all this time spent on jeans, cardigans, shirts and whatnot, socks are pretty neglected. A unique pair of socks show that you’ve made an effort with your whole outfit, not just the main pieces.
I don’t approve on polka dots on much, but they look great on these Rykiel Homme socks. Costing £20 for one pair, it’s probably best you save them for special occasions.
