* Hang clothes according to the type - trousers, dresses, jackets, so that one can immediately see what he has. Investing in slim line hangers will instantly double the hanging space.
* Turn your hangers round so they all face the same direction. Whenever something is worn, hang it back facing the opposite direction. Review your wardrobe again in 6 months, anything still facing the original direction in 6 months should be stored or sold.
