The Merchant, which opened in 2010, is an online and retail shop in Notting Hill selling top end designer wear on consignment. This Friday, they are selling some of Trinny's (of Trinny and Susannah fame) wardrobe with part proceeds going to the Steps2Recovery charity. As I am about double the size of Trinny, I will venture there for the scarves and her other accessories. 
No Knickers and I love the concept of recycling and are so happy to see that are some amazing shops opening up or revamping themselves to look and sell the most stylish fashion.
Other stores we love are the revamped FARA stores, especially the store in Northcote Road, High Fashion Society in South Molton Street and The Dresser in Connaught Village, W2. This list is not exhaustive. Give me time and I will seek out some more! Signing off, Fur Coat
