Where pilling appears first on a garment

Short answer: Pills form first where fabric rubs against fabric or against something else. That is typically under the arms, at the sides, on the inside of the thighs and where a bag or belt sits. Where there is friction, the pills come first.

Friction creates pills

Pills do not form by themselves. It takes movement where two surfaces work against each other and short fibre ends can work loose and tangle. If a garment has a spot that moves a lot against something, you can expect that is where you first see a small grey surface.

Arms and sides come first

The arm moves against the side of the garment all day, and that is why it usually starts there. Under the arms and along the sides the fabric rubs against itself and against the body with every step you take. See bamboo tights for women.

The inside of the thighs

When you walk, the thighs rub against each other, and the fabric between them takes the wear. That applies especially to trousers, tights and underwear that sit close. Here you usually see the first pills, because the movement is repeated thousands of times a day without you thinking about it.

Bags and belts make patches

A strap that lies in the same place every day wears down an area of the fabric. So does a bag that hangs on the same shoulder, and a belt that sits at the same height. Switch shoulders now and then, and move the bag so the wear is spread out. See bamboo undershirt for women.

Feet and socks

In socks it is the heel, toes and sole that rub against the shoe. Here you see pills first, especially if the shoe fits closely or you walk a lot. Make sure the sock sits properly and the shoe is not too big, so the foot does not slide around. See bamboo tennis socks for women.

Can I avoid it

Not entirely, but you can move the bag and turn the garment inside out in the wash. You can also rotate between several garments, so the same fabric does not rub in the same place day after day. Small changes in habits make a difference over time.

Why new clothes pill the most

There are most loose fibre ends at the start, and they wear away with time. It looks worse than it is, because most of the loose material disappears after the first few washes. Once you have removed the pills, fewer usually return.

Does washing less help

Yes. Washing is also friction, and fewer washes mean fewer pills. You do not need to wash a garment after every wear if it is not dirty. Let it air, and wash when necessary on a gentle programme, without cramming the machine.

How to keep an eye on it

Look for pills where the fabric rubs most, and remove them early with a fabric shaver or a comb. The sooner you do it, the smaller they are, and the longer the surface stays smooth. It is a simple habit that extends the lifespan of your clothes.
