I like the suit and the no socks, but the sneakers are too chunky. I think some sneakers with suits look okay, but it appears the leg of his trousers are fairly tapered, and this would definitely require a slimmer shoe in my book. I think a tan dress shoe would have gone better - he could still eschew the socks.
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.
