MANILA, Philippines - When Sarah Jessica Parker and celeb stylist-turned-reality-star Rachel Zoe famously took on the reins at Halston Heritage (and then quietly left the company), they were garbed in plenty of vintage and Heritage Halston while going about the red carpet. SJP even made the dress a major movie event in the second Sex and the City film. Since then, other celebs have taken on the mantle of Halston wearer — from former Zoe client Nicole Richie to Mariah.
