Last week it was revealed the Duchess sent aides to a second-hand dress agency just a few miles from her Berkshire family home to find her outfits.  Her nearly new purchases from The Stock Exchange, in Sunninghill, include the grey Jesire coat dress she wore to a National Portrait Gallery event last month.  Described as a "premier venue for the fashion-conscious bargain hunter", the shop sells unwanted designer gear for clients and takes a 50 per cent cut of the sale price.  We sent Sun stylist Nana Acheampong to the shop to put together a wardrobe that was fit for a princess.  She found top High Streets labels including Kate's favourites LK Bennett and Karen Millen, plus fashion house labels including Chloe.  Nana, 25, said: "Staff revealed the store takes donations from a host of local TV presenters. They get a cut of any sales but anything not sold after five weeks goes to charity.  Bags of style ... Nana Acheampong at The Stock Exchange  "They haven't seen the Duchess in the store but they were really excited when they saw Kate on TV wearing the Jesire dress.  "It looks like the Duchess has a secret shopper and The Stock Exchange are keen for whoever it is to continue shopping there."  Nana managed to put together four outfits for less than £180.  Here, Kate lookalike Chelsea Collins, 22, from Poole, Dorset, models our princess perfect looks.  Stock Exchange price ... Dress and jacket (left), £44 for set, Phase Eight. Original price, £234.
