Ask any denim obsessive how to wash jeans and you will get a passionate answer - sometimes a contradictory one. Never wash them. Freeze them. Wash them after every wear. The truth, as usual, sits in the calmer middle: good denim needs washing far less often than most people think, and when it does, a few small habits make the difference between jeans that fade beautifully over years and jeans that lose their shape, colour and character in a season.
We have been selling designer denim from our Hall Street boutique in Bondi since 1995, and the question comes up at the counter almost daily. Here is the advice we actually give - the same care routine we use on our own most-loved pairs.
How Often Should You Actually Wash Jeans?
Far less than the rest of your laundry. Denim is a hardy twill that does not cling to odour or lose its freshness the way finer fabrics do, and every wash costs a little indigo, a little fibre strength and a little of the shape the jeans have moulded to your body. As a working rule, wash after every eight to ten wears, or when they are visibly dirty - whichever comes first.
Between washes, spot clean marks with a damp cloth and a drop of mild detergent, and air jeans overnight - outside if you can. On this coast, twenty minutes of sea breeze does more to freshen denim than most people expect. Raw and untreated denim rewards even more patience: the longer the first wash is delayed, the more personal the fade pattern becomes, which is exactly why vintage-inspired labels like RE/DONE build their jeans to age this way.
The Right Way to Machine Wash
When wash day does come, the routine is simple and worth following every time. Turn the jeans inside out - this is the single biggest protection against fading and hardware scratching. Close zips and buttons so nothing snags. Then wash cold, on a gentle cycle, with a small dose of mild detergent, and skip fabric softener entirely - it coats the cotton fibres and breaks down the crispness that gives denim its structure.
Cold water matters more than any other setting. Heat is what strips indigo and shocks the elastane that gives stretch styles their recovery - and most contemporary denim, from a skinny to a relaxed straight leg in our women's jeans edit, carries at least a small percentage of stretch. Wash jeans with other denim or dark colours only; that first wash in particular will release indigo, and a stray white tee in the drum will remember it forever.
A wash bag is not essential for denim, but washing like with like is - heavy fabrics tumbling against delicate ones is how knits pill and denim hardware does damage. Keep the load small so the jeans move freely and rinse clean.
Drying: Where Most Damage Happens
If a pair of jeans is going to be ruined, it usually happens in the dryer. High tumble heat shrinks cotton, exhausts elastane and sets creases that never quite leave. Instead, smooth the jeans back into shape while damp - run your hands down the seams, straighten the hems - and hang them to dry, either by the waistband or folded over a line, inside out and out of direct harsh sunlight, which fades indigo just as surely as hot water.
Air drying also keeps the fit honest. Freshly line-dried jeans feel firm for the first hour of wear, then relax back to the shape your body has taught them. That cycle - a slight tightening, then a soft break-in - is exactly how denim is meant to live, and it is why a well-kept pair from labels like AGOLDE or L'AGENCE still looks considered years in, while fast-fashion denim bags out in months.
Why Denim Care Is Conscious Fashion
There is a bigger reason to care about all of this than keeping a favourite pair looking good. Denim is one of the most resource-intensive garments in any wardrobe to produce, which makes extending its life one of the most genuinely sustainable habits available to any of us. Washing less, washing cold and skipping the dryer all reduce the energy and water a pair consumes across its lifetime - and, more importantly, they keep the jeans in rotation for years instead of cycles.
This is also why we stock the denim we stock. Labels like RE/DONE, built on reworking and reimagining vintage denim, and Seventy + Mochi, with its considered approach to production, make jeans designed to be kept - and a pair designed to be kept deserves care that lets it be. Buying better and washing smarter is quieter than any slogan, but it is the version of conscious fashion that actually works.
If you are building a denim wardrobe worth caring for, our full designer denim collection spans jeans, jackets and skirts from the labels above - a current favourite on the floor is the Anine Bing Roy Jean in Pacific Blue, a classic straight leg from the wider jeans edit that will reward every one of these habits.

Your Questions Answered
Should I wash new jeans before wearing them?
For dark indigo denim, one cold, inside-out wash before the first wear reduces dye transfer onto light tops, bags and car seats. For pre-washed lighter denims it is optional - they arrive stable.
Does freezing jeans actually clean them?
No - it is a persistent myth. Freezing dulls odour temporarily but kills nothing and cleans nothing. Airing jeans overnight outside does the same job better, and an occasional proper cold wash does what the freezer never will.
How do I stop black jeans fading?
Wash rarely, cold, inside out, with a detergent formulated for darks, and never tumble dry. Dry them inside out in shade. Fading is cumulative - every heat exposure costs colour you cannot get back.
Can I iron jeans?
You rarely need to - hanging while damp removes most creasing. If you do, iron inside out on a medium setting while the denim is slightly damp, and avoid pressing hard creases into the legs unless you want a tailored look.
How should I store jeans?
Folded flat or hung by the waistband, away from direct sun. Avoid wire hangers pinched at the knee, which leave marks. Give raw denim rest days between wears - the fibres recover, and the jeans last visibly longer.
