His book is interesting and very thought provoking, I haven't bought from CC because I am on a mission to not add to my already huge clothing collection. There are definitely some sobering messages to take on board from what he says.
Personally I am not sure that I could ever just have a wardrobe with a range of very basic well made items in it. He is a bloke, and that makes a difference. For me there are nights out when I want to dress up, special occasions, or days at work when I want to stand out a bit. What I won't do is buy from super cheap stores and probably the most important thing that I intend to do is massively reduce the amount of clothing I buy.
The other thought that I took away from his book is how infrequently any of us wear or use an item until it falls apart or wears out, all credit to you if you do. I am definitely taking that on board, the thought of my unwanted clothing being shipped abroad and dumped is a very uncomfortable one.
