When something is a claim and not wear
Short answer: A fault that comes from production is a claim. Something worn out by use is not. The line lies in where and how the damage arose.
What is usually a fault
A seam that opens without being loaded, a colour that bleeds at the first wash, a hole in a flat area with no abrasion and a garment sewn askew. Those are production faults.
What is usually wear
Holes at the heel and toe of a sock, fabric worn thin under the arms, bobbling after a year of use and elastic gone slack. That comes from wearing and washing. See bamboo socks for men.
How to go about it
Write to the shop with a photo and a short description of when it happened and how many times the garment has been washed. Keep the garment until the case is settled. See bamboo underwear for men and bamboo clothing for women.
