HIGH-OCTANE: This fashion season’s four celebrity-packed weeks did not end with a whimper. The Elie Saab show, which was the last major catwalk event on the Paris Fashion Week schedule, might have been a low-key affair. Not so. Taylor Swift caused a major scuffle there, despite her publicists trying to create a barrier to prevent photographers from snapping pictures of the star. The bizarre “security zone” came in the form of a polystyrene sculpture resembling an iceberg that was manned by a semicircle of bodyguards. Meanwhile, sitting close by, Alain Delon and Virginie Ledoyen smiled for the cameras.
