CRIMSON TALE: Can you imagine a wedding where the bride doesn’t show up? Well, it might not fit into the same category, but Vera Wang won’t be taking a bow at her bridal collection show in New York at 4 p.m. Friday. It’s Freshman Parents Weekend at Harvard, where her younger daughter, Josephine, attends. So Wang had to pick one place to be, and Harvard (and her daughter) obviously won out. “Vera cannot miss that,” said a Wang spokeswoman.
