Inspired by the Tommy Hilfiger ad campaign for this year - "Meet the Hilfigers" - this is definitely a reference to the polo/nautical/tennis look suggested.  We've unearthed our inner Hilfiger (or Royal Tenenbaum) and donned the red white and blue combination. The sweater is vintage, pants are H&M and flats are Kelly and Katie. By the way, if you happen to have the preppy look down you could snap a shot and send it to Tommy... you never know, you could end up spending a "prepped-out weekend" somewhere.
