What a pair of knickers goes through in a year
Short answer: A pair of knickers is exposed to friction, sweat, washing and drying almost every day. There are no fixed figures, but the general mechanisms explain why fabric, fit and care matter.
Close to the skin every day
Knickers are the clothing closest to the body, and they are usually worn daily. That means they are exposed to warmth, moisture and movement again and again. Some people change every day, others more often. It depends on habits and activity. Because they sit close, you quickly notice if seams chafe or the waistband squeezes, so it is worth choosing a fit that is comfortable all day long.
Friction and movement
When you walk, sit and bend, the knickers move with your body. Friction against the skin and other clothes can in time make the fabric thinner, especially at the leg openings and in the side seams. Smooth fabrics and flat seams wear less. If you face a lot of friction, for example during training, it can help to choose a fabric that does not rub. How fast it goes depends on the material, the fit and how much you move.
Washing and drying
Knickers are washed often, and that wears on the elastic. Wash them at 30 to 40 degrees, preferably in a small laundry bag so that they do not catch on other clothes, and avoid putting too much fabric softener in the machine, as it can make the fabric less breathable. Dry them without high heat so the elastic lasts longer. You can easily wash them with other underwear. See bamboo shorts for women if you want a longer style for everyday wear.
Elastic and fit over time
Elastic loses its spring with time, and that is perfectly normal. You notice it when the waistband sits looser or the knickers slip. Many replace them when they no longer fit well or when the fabric is thin. Give your knickers a rest day now and then, so the elastic can draw back together. It is practical to have several pairs and rotate them, so that the wear is spread. The same applies to other clothes you wear close to the body in everyday life.
At home and on the go
Loungewear and underwear are closely linked in everyday life. If you wear soft, loose things at home, the body gets a break from tight clothing, and the underwear is worn less hard. See home and homewear in bamboo. Many also change into something soft when they come home. For those who prefer a bra without underwire, it is often a more relaxed solution that many choose for everyday wear. See bamboo bra without underwire.
Frequently asked questions
How often should knickers be replaced

Should knickers be washed after every wear
Yes, underwear is usually washed after each wear. Wash at 30 to 40 degrees and follow the care label.
Does tumble drying damage knickers
High heat can wear the elastic, so air drying is gentlest. Follow the care label.
