Cost Per Wear: How to Buy Fewer, Better Clothes
The simple sum that changes how you shop, plus the checks that tell you whether a garment will actually last long enough to earn its price.
Cost per wear is the price of a garment divided by the number of times you wear it. A £300 jacket worn 100 times costs £3 a wear; a £40 top worn twice costs £20. It is the clearest way to compare clothes, and it tends to reward pieces that are well made, versatile and easy to look after.
This guide shows how to use the sum properly, where it can mislead you, and what to check in a shop before you trust it.
How to calculate cost per wear
The basic formula is simple: price divided by wears. The honest version adds two things most people forget.
- Add the running costs. Dry cleaning, repairs and alterations belong in the total. A dress that needs professional cleaning after every outing may cost more over its life than its price tag suggests.
- Estimate wears realistically. Count how often you actually go out in a typical month, then multiply by the number of seasons you expect the piece to suit. Be strict. An evening dress worn once a month for three years is 36 wears, not 200.
- Subtract what you might get back. Well-made pieces often resell or can be passed on, which lowers the true cost further.
So a £250 dress, cleaned six times at £15, worn 36 times, comes to roughly £9.50 a wear. A £60 dress that loses its shape after five wears comes to £12. The cheaper dress is the more expensive one.
Why buy less buy better makes sense
The "buy less buy better" idea is partly about money and partly about waste. The Ellen MacArthur Foundation's report A New Textiles Economy, published in 2017, found that clothing production had roughly doubled in the previous fifteen years, while the clothes themselves were being worn less.
Wearing what you own for longer is one of the simplest fixes. The UK charity WRAP, in its case study on clothing durability, says that extending the life of clothes by nine months can cut their carbon, water and waste footprints by up to a fifth. For anyone wondering how to shop sustainably, that is a useful starting point: the greenest garment is often one you already have, and the next greenest is one you will keep.
The catch: price does not guarantee durability
A higher price does not automatically mean a longer life. In February 2026 WRAP and the Leeds Institute of Textiles and Colour published a three-year study of more than 200 garments, and their durability report found that price, brand and fibre content did not reliably predict how well a garment would last.
That means the sum only works if you judge the garment itself. Spending more is a bet, and you should check the odds before you place it.
What to check before you buy investment pieces
Investment pieces earn the name through construction and versatility. Before you buy, take the garment to good light and look closely.
- Seams. Pull gently either side of a seam. It should not gape or show daylight. Look for generous seam allowances, which leave room for alterations.
- Lining. A lined jacket or skirt hangs better and lasts longer. The lining should be slightly loose so it does not pull the outer fabric.
- Fabric density. Hold knitwear and lace up to the light. A tighter, denser structure usually pills and snags less than a loose one.
- Finishing. Check hems, buttonholes and zips. Loose threads and puckered zips are warnings.
- Care label. A piece that can be hand washed is cheaper to keep than one that must be dry cleaned every time.
- Fit. If it needs more than a simple alteration to fit, you will probably not wear it often enough.
Then apply the wardrobe test. Name three things you already own that it goes with, and three occasions you will wear it to in the next two months. If you cannot, the numbers will never add up, however good the garment is.
Where cost per wear works best
Some categories reward the maths more than others. Tailoring, coats, knitwear and simple black dresses tend to be worn the most, so they suit a bigger spend. A good blazer can go to dinner, the theatre and the office in the same week.
Trend pieces and very specific occasion wear rarely earn their price back, so keep those budgets lower or borrow. A small, coordinated wardrobe makes the sum easier, because every new piece multiplies the outfits you already have. Our guide to building an evening capsule wardrobe explains how to choose those core pieces, and our notes on quiet luxury for the evening show how understated, well-cut clothes keep looking right for years.
Keeping the number low after you buy
The figure keeps falling for as long as you keep wearing something, so care is part of the equation. Air pieces between wears, brush wool, store knitwear folded, and fix small problems such as a loose button straight away. A tailor can take in a waist or shorten a hem for far less than a replacement costs.
It also helps when a brand keeps making the pieces you rely on. At Notte & Noir every piece is restocked after it sells out, and sold-out sizes have a waitlist; you can read why in our piece on restocks and waitlists, or learn more about our vision and mission.
