How can the cloth use long time , or if the clothes are you asked? You should know your brands better. For example, you bought a jeans, but can you understand material it’s an original or a duplicate?
any case, you feel that the standard of quality is the same here, so I will give you tips on how to look at how the clothes are durable:First, always consider design and fabric, consider compatibility. For example, denim is much better than picking up a figurative pound, so it is more suitable for a garden than a loose trunk, but cooler clothes can be as good as hot.
Seaming is important for quality and optics, so always check the seams. They need to clean, straight, flat bed. You do not even need places where you have loose threads, clear noise, straight lines, pickering, or mangrove time. Check the fabric with a cloth on the both sides of the hole and scratch the skin and do not separate it. This is more important for the load-carrying force, but it’s a good indicator of quality.
Also, if there are patterns of pattern from cosmetic perspectives, there should be rows on both sides of the pattern. This is not important for a long term perspective, but rather a different look.
