What should I do if the suspender waistband is too big?

Fold the sides of the belt slightly inward according to your own needs, and then sew. If you are not sure, don't make it yourself, send it to the tailor's shop.

Renovation style with shoulder strap:

Make two belts of the same color as trousers and sew them on the belt. With the restraint of the sling, it is not so inconvenient when the waistband is big. It is also a fashionable way to wear a coat in the waistband when you wear it out.

Note: This method is only applicable to pants with excessive waistline. If the hip circumference and crotch are beyond your size, I suggest you take them to a tailor's shop for a big transformation ~

Extended data:

Suspenders refer to trousers with shoulder straps at the waist. The name of modern trousers, also known as "rice trousers" or "overalls", is to add a chest protector (commonly known as rice trousers) to ordinary trousers or shorts, and tie a strap instead of a belt, hence the name.

Because the shape of these pants is changed from the style of mechanic's work pants, they are also called work pants. Nowadays, suspenders are mostly worn as children's clothes for men and women, and some young women wear them as daily clothes.
