The long awaited New York branch of Topshop is finally open! The shop opened at 11am Eastern Standard Time (4 o'clock here) and is already crowded with people dying to get their hands on stylish goods. Kate officially opened the store alongside Sir Philip Green (although she was only present for a brief moment) in an emerald green floor sweeping gown from her latest collection with a pair of YSL patent platforms. In this week's Grazia magazine the supermodel says that emerald green is one of her favourite colours, in fact, she calls it "gorge". See below to copy Kate's look.
