According to a Denim Expert, There’s Only One Reason You Should Wash Your Jeans Inside Out

You probably toss your jeans into the washing machine the same way you toss in everything else – right side out, maybe bunched up, maybe not even thinking about it. And honestly, why would you? Laundry already takes long enough without adding extra steps. But if you have ever pulled a favorite pair of jeans out of the dryer only to notice they look noticeably lighter than when they went in, you already know something is going wrong. The fix might be simpler than you think, and it starts before you even close the machine door.

Why your favorite pair keeps losing its edge

Denim has come a long way from pure workwear. Today it sits comfortably in the world of high fashion, which also means prices have climbed considerably. When you are spending serious money on a single pair, it makes sense to protect that investment. Yet most of us still treat jeans like any other garment on laundry day, tossing them in without a second thought.

Frank Pizzurro, a denim expert at Brooklyn Denim Co. who has been selling raw denim products and making jeans for 14 years, says there is really only one reason to flip your jeans before putting them in the wash. It all comes down to color preservation. So if you have been wondering whether that old laundry tip your friend once mentioned actually holds up – it does, but perhaps not for the reasons you assumed.

The single benefit that makes flipping worth it

According to Pizzurro, turning jeans inside out before washing keeps the fabric holding its color for a longer period of time. When denim is washed right side out, the indigo dye on the surface rubs against other fabrics in the load. That friction accelerates fading. Flip the jeans inside out, and the indigo essentially only makes contact with itself, which means far less color loss per cycle.

In practical terms, your jeans will stay darker longer if you consistently wash them this way. That is the entire rationale – not structural integrity, not shrinkage prevention, just color. And for anyone who has ever bought a deep indigo pair only to watch it turn pale blue within a few months, that single benefit is more than enough motivation to add the extra five seconds to your routine.

Pizzurro also recommends using cold water for every wash and hanging jeans to dry afterward rather than throwing them in the dryer. Cold water is gentler on the dye, and skipping the dryer helps the denim itself last longer. Together with the inside-out flip, these small adjustments form a straightforward care routine that protects both color and fabric.

How often you actually need to launder denim

Here is where things get interesting. Pizzurro advises wearing new jeans as long as you possibly can before that first wash. The logic is that unwashed denim breaks in and gradually shapes to your body, creating a fit that is uniquely yours. Washing too early interrupts that process.

Once your jeans are broken in, the recommended frequency is still far less than most people assume. If you wear the same pair nearly every day, Pizzurro suggests washing them every four to eight weeks. If you only pull them on occasionally, you can go months between washes. Yes, months.

The reason for restraint is fiber preservation. Washing denim too often breaks down the fibers more quickly, and that is especially true for jeans that contain stretch fibers – which many modern pairs do. Overwashing a stretch-blend pair can shorten its lifespan noticeably.

Of course, context matters. If your jeans see heavy-duty action – construction work, landscaping, or similarly demanding tasks – more frequent washing is understandable. Designer pairs that mostly see dinner tables and office chairs can afford to wait longer between cycles. And if you are wearing your best denim through a hot, humid summer, you may want to bump up the frequency slightly. Just remember to turn them inside out first.

The takeaway for your next laundry day

The rule is refreshingly simple. Flip your jeans inside out to protect the indigo dye, wash in cold water, and hang dry. Beyond that, resist the urge to wash them after every wear – every four to eight weeks is plenty for daily-wear pairs, and occasional-wear jeans can go even longer. These small habits do not require special products or extra time, yet they can keep your denim looking richer and feeling stronger for far longer than the standard toss-and-tumble approach. Your jeans – and your wallet – will thank you.
