1, elastic band adjustment: it can be adjusted by tightening or loosening the elastic band. Find the elastic band in your pocket and gradually adjust the tightness of the elastic band according to your waistline and comfort. Tightening the elastic band can make the belt fit the waist better, and relaxing the elastic band can increase the comfort.

2. Buckle adjustment: adjust with buckle. These buckles usually have multiple buckles. You can choose the appropriate buckle to adjust the tightness of your wallet according to your own needs. Insert the buckle belt into the corresponding buckle ring to ensure that the waistband is tight, but not too tight.

3, adjust the position: in addition to adjusting the elastic band or buckle, you can also try to adjust the position of the wallet. Put the belt in different positions around the waist, such as above or below the waistline, to find the most comfortable and stable position.
