This Wired story makes for very interesting reading. It indirectly explains why it is so hard to shop for clothes. Even with the seemingly endless variety there is overwhelming monotony - season after season, store after store. Once you have stocked up on the wardrobe staples, the rest gets much harder if your goal is to find clothes that express your individuality.
There is many ways to join the sheep herd but nearly none to be a snowflake. Some of my friends shop for clothes at consignment stores because it easier to come by something unique there. Then there are those like Mrs L, who I knew many years ago, who have their all their clothes tailored in Hong Kong - completely bespoke and very much a snowflake.
