Spotted: Reese Witherspoon in costume on the set of Water for Elephants, looking perfectly on trend for Fall 2010. Wearing jodhpurs, a plaid vest and sleek riding boots, the blond actress was the epitome of equestrian chic. Of course, we wouldn't expect anything else from Witherspoon, who always looks classically pulled together. Water for Elephants co-stars Twilight's Robert Pattinson and hits theaters in 2011.
