Cost Per Wear: The Only Fashion Maths That Matters

Here is a sum that ruins impulse buying forever, in the best way. Take what a thing cost, divide it by the number of times you've worn it. That's cost per wear, and it's the only number that describes what a garment has actually charged you.

Run it on your own wardrobe once and the words cheap and expensive stop meaning what you thought they meant.

The sum, on real clothes

A $17 top bought for one night out and worn twice costs $8.50 every time you put it on. A $200 coat worn four times a week through two winters — call it 200 wears — costs a dollar. The coat is more than ten times cheaper, and it's the one that felt like the extravagance.

Nothing about that is an argument for spending more. It's an argument for counting wears, because the wear count does all the work in that equation and it's the half nobody thinks about at the till.

“Price is what you pay once. Cost per wear is what the thing charges you every time you get dressed.”

— The Bestis Editors

The thirty-wear test

The quickest version of this is a question to ask before anything enters your wardrobe: will I wear this thirty times? Not could I, in some imagined life — will I, given the weeks I actually have.

It's a brutally effective filter. Thirty wears is roughly once a week for a season, or twice a month for a year. Things that pass are the things you reach for; things that fail are usually bought for a version of your life that exists mainly on a Saturday afternoon in a shop.

What actually drives the number down

Once you're counting wears rather than prices, the things that make a garment worth owning change:

• Does it go with at least three things you already own? A piece that needs a whole outfit built around it starts at a wear count of nearly zero.
• Is it comfortable for a full day? Discomfort is the most common reason a promising piece stops being worn, and it never improves.
• Will it survive being washed properly? A thing you're afraid to clean is a thing you'll stop wearing.
• Is it tied to one trend or one occasion? Both cap the wear count before you've worn it once.
• Can it be repaired? A hem, a button and a seam are the difference between fifty wears and two hundred.

Where swapping breaks the equation

Cost per wear has an obvious weak point, and it's the thing hanging in your wardrobe right now that you no longer wear. Its wear count has stopped. Whatever you paid is fixed, the denominator has frozen, and every day it hangs there the number gets no better.

Swapping is the only move that fixes that piece. It goes to somebody who will wear it — the wears keep accumulating, just not on your account — and something arrives that you'll actually reach for, at a price that makes the sum almost silly. Divide nearly nothing by thirty wears and you get a number no shop can compete with.

The version that sticks

You don't need a spreadsheet. You need two habits: ask the thirty-wear question before anything comes in, and move things on while they still have wears left in them rather than after they've sat unworn for two years.

That's the whole discipline, and it happens to be the most sustainable thing you can do with clothes — not because you bought something labelled sustainable, but because everything you own is being worn by somebody, for as long as it lasts.

On Bestis, the piece you've stopped wearing is somebody's next favourite thing, and theirs is yours. Swap within circles you trust, keep the wear count running, and let cost per wear be the number you're quietly winning at.
