Before buying or discarding anything, write down how your last four weeks were actually spent: how many days at a desk, how many on your feet, how many that needed something better than ordinary. Then build for that ratio.
Nearly every overstuffed wardrobe is built for a life its owner has about six days a year. The occasion pieces are not the problem on their own; the problem is that they were bought with the budget the everyday pieces needed.
Two neutrals, one transition colour, two accents. The neutrals carry the bottoms and the outerwear, the accents live on the tops where they are seen and remembered.
This is the step that decides the arithmetic. Every piece has to match most of the others, and matching is mostly a colour question. Past the fifth or sixth colour each addition matches less of what you own, so the outfit count starts falling.
This is where a wardrobe built in Turkey differs from the lists written for northern Europe. İstanbul and the coasts spend more of the year in the transition than in deep winter, and the interior swings much harder between day and night than either.
Practically: layers beat weight. Three thin things you can take off carry more days than one heavy coat, and they keep working in the weeks either side of winter, when a heavy coat is simply wrong.
The seasonal cut on this site shows the shape of it — of the forty pieces, thirty-six get worn in autumn and twenty-two in winter. The wardrobe narrows in winter; it does not get replaced.
Quality is not a price bracket, and in a market with a lot of domestic textile production it is genuinely possible to buy well without buying expensively — if you can read the garment rather than the label.
Six checks, five minutes, in the shop: the fibre ratio on the care label, the fabric held up to light, a squeeze in the fist to see whether the crease falls out, the seam allowance turned inside out, the lining, and the zip.
Around eighty percent of the budget belongs to a small number of core pieces you will wear weekly for years. The measure is cost per wear, not price: a coat worn two hundred times is cheap at almost any price, and a trend piece worn twice is expensive at any discount.
The common mistake runs the other way round — buying the trend piece cheaply and the classic piece cheaply too, which produces a wardrobe that looks tired within one season.
At the end you are looking for the two or three missing pieces that connect what you already own, not for more pieces. A single cardigan in the right neutral can open more outfits than five new tops in colours that match nothing.
The calculator on this site does exactly that arithmetic: tap what you own and it returns how many outfits those pieces produce, a score out of 100, and the three additions that would open the most new combinations.
