JEAN-IUS COMING: Famous designers are so busy that they rarely make personal appearances at their stores. But the Calvin Klein will be at Calvin Klein’s in South Coast Plaza today. It’s his first visit since the store opened a year ago. . . . “We’re ecstatic about it,” says store manager Allison Clifford. But mall shoppers beware: The store will be closed. Klein will review his new summer line with by-invitation-only customers.
