A/ There are two parts to this question. When I am buying them I either take someone whose opinion I trust or go it alone in a shop whose clothes I trust. When I get them home clothes are hung in my wardrobe in order of shirts, skirts, trousers and jerseys. I can tell 95% of my clothes by using my sense of touch to differentiate between the shapes of the collar, length of the sleeve etc with my memory doing the remainder of the identifying. If I buy the same style top say, but in two different colours, I make a slit in one of the labels in order to tell it apart from the other one.
