You probably recognise it: you start your day comfortably, but after a few hours you notice your underwear riding up. You constantly have to adjust it, which is not only irritating but also affects your comfort and confidence.
Underwear riding up is a common issue, but fortunately one that is easy to solve – as long as you understand what causes it.
In this blog, you’ll discover the main causes and how to make sure your underwear stays perfectly in place all day long.
Why does underwear ride up?
Underwear should fit like a second skin. When it doesn’t, movement occurs in the fabric. And that movement gradually causes the fabric to shift upwards.
This usually isn’t caused by just one factor, but by a combination of several. Think of an incorrect fit, less suitable materials, or worn-out elastic.
What many people don’t realise is that underwear is actually quite technical. The balance between stretch, fit and material determines whether it stays in place or starts to move.
The fit: the most important factor
The most common cause of underwear riding up is an incorrect fit. When underwear is too tight, tension builds up in the fabric. With every movement (walking, sitting or bending), the fabric is pulled upwards. This is especially noticeable with short-leg styles, such as trunks or briefs chosen in a size that’s too small.
On the other hand, a fit that’s too loose can create excess fabric. This fabric can bunch up and gather, which ultimately also leads to it riding up.
The ideal fit follows the body without feeling restrictive. Your underwear should move with you, not against you.
Leg length makes the difference
Not every type of underwear is equally prone to riding up. Leg length plays a major role. Shorter styles, such as trunks, have less grip on the upper leg. As a result, they are more likely to ride up, especially if the fabric doesn’t fit perfectly.
Boxer briefs with slightly longer legs tend to have this problem less. The extra length provides more stability, helping the fabric stay in place. This doesn’t mean trunks are uncomfortable by definition, but it does mean that the combination of fit and material becomes even more important.
The material: often overlooked, but crucial
In addition to fit, the material is a key factor when underwear rides up. Cheaper or less elastic materials lose their shape more quickly. As a result, the underwear can’t properly follow your body’s movements, causing it to shift.
Friction also plays a role. Fabrics that are less smooth don’t “grip” the skin as well, allowing the material to slide upwards more easily during movement.
Materials such as TENCEL™ Modal, used in Mellowood, offer a clear advantage. They combine softness with elasticity, allowing the fabric to move naturally with your body without shifting.
The result is underwear that stays in place, no matter how active your day is.
Wear and tear: when your underwear no longer does its job
Even the best underwear has a lifespan. Over time, the elastic can weaken and the fabric loses its original shape. You’ll often notice this when your underwear starts riding up. Where it once fit perfectly, it now feels looser or less stable.
Many people wear worn-out underwear for too long. This reduces comfort and leads to irritation that could easily be avoided. A good rule of thumb: if your underwear no longer does what it should, it’s time to replace it.
How can you prevent your underwear from riding up?
The good news is that in most cases, you can completely prevent this issue by making conscious choices. It starts with choosing the right size. This may sound obvious, but it’s often underestimated. Take the time to find what truly fits well, instead of sticking with what you’ve always worn.
It’s also wise to choose a style that suits your body and daily activities. Do you move a lot or experience chafing between your legs? Then boxershorts with longer legs often provide more stability.
The material also plays a big role. Choose high-quality fabrics that retain their shape and move well with your body. This prevents the fabric from shifting or rolling up.
Finally, care is important. Wash your underwear according to the instructions and avoid excessive use of the tumble dryer. This helps maintain elasticity and fit for longer.
