“Take Ivy” is full of students wearing shorts, untucked oxfords and Weejuns without socks. This begs the question: Did the look originate on Yankee campuses, or did the practice originate in the South, with Southern students taking the look North with them when they headed off to college?

Made in 1989 and set in Myrtle Beach, South Carolina in 1963, “Shag” shows guys staying cool in the humid Southern summer dressed in such trad fare as short-sleeved madras shirts, t-shirts, canvas sneakers, chinos and oxfords. Not to mention Weejuns, the perfect shoe for shaggin’ with a waitress on roller skates, as the guy in the yellow button-down does in the screenshot above.

“Shag” stars Annabeth Gish, who’s previously appeared on Ivy-Style, and Phoebe Cates, dream girl of any boy who came of age in the ’80s. There’s also Bridget Fonda, whose figure will not escape your notice.

With its Southern setting, “Shag” is more conservative than the New York-set “Dirty Dancing,” which was made two years earlier and also set in 1963. But whereas “Dirty Dancing” features a post-’60s inversion of values in which the Yale-bound med student is the villain, while the leather-clad greaser is the hero, the leading man in “Shag” is a bit of a n’er-do-well, but still bound for Yale, making him bad boy and husband material all in one. What a catch.

The movie’s soundtrack draws on that carefully edited mixture of R&B and doo-wop known as Beach Music. — CC
