Let's get straight to it — here's what actually matters on this one.

• Pilling happens when short, weaker fibers work loose and tangle into small balls, usually at friction points like underarms and cuffs.
• Lower-quality or shorter-staple fibers pill more than long-staple cotton or high-quality wool, which is why cheaper fabric pills faster.
• A fabric shaver or pill comb removes existing pills safely without damaging the weave underneath.
• Washing inside out and reducing friction with other rough fabrics (like zippers or velcro) in the same wash load slows future pilling.

The fit-and-fabric-health takeaway: Pilling is a visible, physical sign of fiber wear at exactly the spots where fabric rubs against skin most.
