Well, I for one stray away from wearing no socks or low ones with any suits... I agree about the sneakers, they are a bit chunky. But honestly I think he'd have looked more well put together with some regular white athletic socks or (even better) a good pair of argyle ones. As for slim sneakers, you can't get any slimmer than Chuck Taylor. I think they're taking hints from GQ the way they're adding pinstripes and plaids to their colours nowadays.
