Here's something we never do - the answer to last week's tent-to-salon blind item was Zac Posen. But it's not anymore because KCD's request form (where you list the shows you'd like to attend next to their time and place) says that Zac's show will be held at the Altman building - a popular albeit small Fashion Week venue that's played host to Costello Tagliapietra, Charlotte Ronson and Sophie Theallet in the past. This is strange because a) It's small. b) Zac was one of the major designers IMG'd managed to hold on to. c) Zac's shows ooze glamour, which the Altman building does not. Good thing his dresses are spectacular enough to make up for it.
