A pair of raw denim jeans gets better with every wear, right up to the point where it starts to fall apart. That is not the end. Some of the most admired pairs on DENIMHEAD are covered in darning, patched at the crotch and on their second set of hems, and they wear their repairs like the rest of their story.
This guide covers the common failures, what can be done about each, and how to tell when a pair is worth saving.
Catch it early
The most important repair advice is also the simplest: fix things while they are small. A thin patch of fabric is quick and cheap to reinforce. A hole that has spread across the crotch is a bigger job, and it can mean losing some of the fades around it.
Check these areas every few weeks, especially once you are past a few hundred wears:
- The crotch and inner thighs. Hold the jeans up to a light. If you can see light through the fabric, it is ready for reinforcement.
- Back pocket corners. Where wallets and phones rub, the corners wear through.
- Belt loops and the waistband. Loops can tear away at the top, especially if you hang heavy items off them.
- Hems and knees. Hems fray with ground contact; knees can split along the honeycombs on older pairs.
When you post a progress photo, a quick shot of the crotch is worth including. Members are good at spotting a thin patch you might have missed.
Darning: the workhorse repair
Darning is the standard fix for thinning fabric and small holes. A repairer backs the weak area with a patch of denim on the inside, then sews back and forth over it in tight rows, usually on a darning machine, so the new stitching takes the place of the worn fabric.
Done well, it is strong and surprisingly discreet, especially when the thread colour is matched to the faded denim around it. Done badly, it can be stiff and lumpy. If you care about how a repair looks, ask to see examples of a repairer's work before you hand over a favourite pair.
Small holes and thin spots can be darned by hand too, with patience, a needle and some denim scraps. It will not be invisible, but plenty of people prefer the look.
Crotch blowouts
The crotch is where raw denim usually gives up first. Friction between the thighs, plus the stress of sitting and cycling, wears the fabric through faster than anywhere else. A "blowout" is when that wear becomes a tear.
The fix is the same as for other worn areas, just bigger: a backing patch on the inside and dense darning over the top. On a serious blowout, a repairer may need to reinforce the seams as well. It is a well-practised job at any good denim repair service, and it is almost always worth doing on a pair you love.
To delay it:
- choose a fit with some room through the thigh if friction is a problem for you,
- reinforce early, as soon as the fabric thins,
- and keep an eye on wear if you cycle a lot.
Hems and chain stitching
Hems take a beating from shoes and pavements, and they are also one of the details enthusiasts care about most. Many raw denim jeans are hemmed with a chain stitch, traditionally on vintage machines such as the Union Special 43200G. With wear and washing, a chain-stitched hem twists slightly and produces roping, the diagonal, rope-like fade many people look for.
If a hem frays or the stitching fails, a chain-stitch hemming service can redo it. Some independent denim shops run their own machines and will re-hem or shorten jeans. A few things to know:
- Chain stitch can unravel if a loose thread is pulled, so trim stray ends rather than tugging them.
- Re-hemming shortens the leg a little each time, so think about whether you want stacks or a cuff before you commit.
- A fresh hem is dark next to faded legs. It catches up with wear.
Free repair programmes
Some brands will repair their own jeans, which is well worth knowing before you buy.
Hiut Denim, the jeans maker in Cardigan in Wales, offers free repairs for the life of its jeans: you cover the postage, and they ask for the jeans to come back washed. Nudie Jeans runs free repairs at its own Repair Shops and partner stores, for any pair of its jeans regardless of when or where it was bought, and offers a repair kit for people who are not near a shop. Check each brand's current terms before sending anything off, since details change.
If repair support matters to you, it is a fair thing to weigh up when choosing your next pair. Hiut Denim and Nudie Jeans are two brands well known for repairing what they sell, and you can compare prices on hardstoc when you are ready for a new pair. Whatever you wear, you can log every repair on DENIMHEAD to keep the story of the pair in one place.
When to retire a pair
Almost anything can be patched, but not everything should be. Consider retiring a pair when:
- the fabric is thin across large areas, so every repair just moves the tear somewhere else,
- the repairs have changed the fit so much that you no longer reach for them,
- or the cost of the next repair is more than the pair means to you.
Retiring is not the same as throwing away. Retired pairs make excellent donors for patches on your next pair, and plenty of members keep their first pair as a record of where it all started.
Keep the story going
Every repair is part of the history of a pair. Note it in the journey notes on the item in DENIMHEAD, alongside the wear count when it happened, and photograph the repair when it comes back. Future you, and anyone looking at your fades, will want to know that the crotch was darned at 400 wears and the hems redone at 600. That is the kind of detail that makes a well-worn pair worth more than a new one.
