1. Aesthetics: Some designers may deliberately choose the design of seamless edges to increase the sense of leisure and fashion of clothing. This design is usually used in fashion trends to meet the aesthetic needs of current consumers.
2. Comfort: For some light or soft fabrics, such as silk and linen, wrapping may make clothes feel too tight and uncomfortable. Therefore, these fabrics usually do not need to be hemmed.
3. Durability: For some heavy or tough fabrics, such as denim, crimping may reduce its wear resistance and durability. Therefore, these fabrics usually do not need to be hemmed.
However, for some clothes that are easy to loose or come off the thread, it is very necessary to lock the edge to ensure the aesthetics, durability and comfort of the clothes.
