It says the hem can be cut with scissors, but won't it fray after cutting?

Turn-up refers to a style where the hem is folded upward once to the outside and finished. For these pants, you can adjust the length according to your body shape by cutting that folded hem with scissors ^[1]. The structure leaves the choice of deciding the length up to the wearer.

There is something to do before cutting. In general, it is recommended to put on the shoes you usually wear, stand in front of a mirror to check the desired length, mark both sides with chalk or sewing pins, and shorten it bit by bit while leaving plenty of room. Fabric once cut cannot be undone, so it is safer not to cut directly to the target length all at once.

Fraying depends on the fabric weave and finish. Generally, if raw cut edges are left as they are, threads tend to unravel bit by bit through washing and friction, so many people have it finished at an alteration shop by overlocking or folding and stitching the hem. However, because there are no instructions regarding this product's fabric composition or recommended finishing after cutting, how much it actually frays has not been confirmed.
