to the op: many of the pieces in that shoot can easily be found at a thrift store, tweed or corduroy sportcoats especially. if they have leather elbow patches that's a plus, these could easily be paired with a button down under a college sweater or a sweater vest. one thing i did a lot of was buy a ton of beat up dress shoes, one pair of black and one pair of brown/burgundy brogues, a pair of plain loafers, and maybe just a plain pair of captoes. you can easily find these for around 10 bucks. recently urban's taken on some of these and selling them for 38 bucks in store.
seller walneal is letting a bunch of sweet sportcoats go, for really good prices too: http://www.styleforum.net/showthread...28#post2274228
as far as buttondowns are concerned, i'd reccommend a decent number of solid oxford shirts, two whites, a blue, and a pink or mint green is a good start, and checks like tattersall, candy stripe, or prince of wales. many of these can readily be found in a thrift store, albeit sometimes you'll have to shop in the boys' or women's sections to find a good fit. YMMV though. but i mean, if you pair the beat-up shoes, a well-fitting buttondown, and a classic-looking jacket it's a great way to tap into the prep-chic trend for cheap, especially at a place where it's most appropriate.
