Cost per wear: the number that actually changes how you shop

There’s a simple calculation that, once you see it, changes how you look at price tags forever.

Take the price of a garment. Divide it by the number of times you’ll realistically wear it. That’s your cost per wear.

A €120 wool jumper worn twice a week for three winters — roughly 150 wears — costs €0.80 per wear. A €25 fast-fashion jumper that pills after two months and gets worn maybe 12 times costs €2.08 per wear. The “expensive” jumper is cheaper by a factor of 2.5.

Why this matters for impact too

The same logic applies to environmental footprint, and the effect is even more dramatic.

That wool jumper carries an estimated production footprint of around 27 kg CO₂e. Spread over 150 wears, that’s 0.18 kg per wear. The cheap acrylic alternative might have a lower production footprint — say 14 kg CO₂e — but worn only 12 times, that’s 1.17 kg per wear. The “lower footprint” garment has six times the impact per use.

The production footprint tells you what it cost the planet to make. Cost per wear tells you what it costs you per use, and that’s the number that actually reflects your impact as the person wearing it.

The psychology of price tags

We’re trained to compare prices at the point of purchase. €120 versus €25 — the €25 wins on instinct. But that comparison ignores the most important variable: how long the thing lasts.

The fashion industry benefits from this blind spot. A business model built on selling high volumes of low-durability garments depends on you comparing purchase price, never cost per wear. If every price tag also showed the expected cost per wear, buying patterns would shift overnight.

This isn’t about shaming anyone for buying affordable clothing — budgets are real constraints, and not everyone can spend €120 on a jumper. It’s about making the full picture visible, so that when you do have a choice, you can make it with open eyes.

How to estimate it honestly

The tricky part is predicting how many times you’ll actually wear something. We tend to overestimate. That jacket you imagine wearing “all the time” might sit in the wardrobe eleven months a year. Here are a few honest heuristics:

Daily basics(T-shirts, underwear, socks) get worn and washed frequently. A well-made T-shirt might last 100+ wears. A poorly made one: 20–30 before it loses shape.

Workwear staples(trousers, shirts, blouses) that you rotate through a weekly lineup: 50–100 wears over their lifetime is realistic.

Seasonal outerwear(winter coats, rain jackets): you might wear them 60–90 days per year. A coat that lasts five winters: 300–450 wears. One that lasts one season: 60.

Occasion wear(suits, formal dresses, party outfits): be honest. If you’ll wear it twice, the cost per wear is half the price tag. That’s not necessarily wrong — but know it going in.

Trend piecesare the highest cost-per-wear items in most wardrobes. By definition, they have a short window of relevance. A €40 trend piece worn 5 times before it feels dated: €8 per wear. That’s the most expensive clothing you own.

The one question worth asking

Before buying anything, there’s one question that captures all of this:

Will I still be wearing this in two years?

If yes, the cost per wear will be low, and the per-wear footprint will shrink with every use. If you hesitate, that hesitation is information.

Kleerdrobe can’t answer that question for you — it depends on your taste, your lifestyle, your wardrobe. But we can show you the numbers that make the question worth asking.
