Sort by shape, not by colour
Colour-coded rails photograph beautifully and are useless for dressing. You do not think "I want something burgundy" in the dark at seven in the morning; you think "I need a jumper and trousers" or "I need something to wear over this". So group by category: trousers together, skirts together, shirts, knitwear, layering pieces, dresses, coats. Within each group, then arrange by colour if it pleases you — light to dark is the easiest to scan.
Keep the current season at eye level and arm's reach. Everything you will not touch until May goes to the top shelf, the back of the rail, or under the bed in a breathable cotton bag rather than plastic. Store woollens clean, since moths are drawn to the traces of skin and food on worn fibres, not the wool itself. Add cedar or lavender if you like, but the clean part matters far more.
Hang what creases, fold what stretches
The rule is simple and solves most wardrobe damage. Shirts, blazers, dresses, structured trousers and coats hang. Knitwear, jersey, sweatshirts and anything heavy enough to stretch out over its own shoulders gets folded flat. Hanging a chunky jumper for a winter is how you end up with those two little peaks at the shoulder line that never brush out.
While you are at it, deal with the hangers. A rail of mismatched wire, plastic and wooden hangers wastes several centimetres of space and makes everything look jumbled. You do not need an expensive matching set; you need one type, slim, in sufficient quantity. The uniformity is not about aesthetics, it is about being able to see.
