Transform your waistline: first determine your waistline size, then measure the waistband size of this pair of jeans that needs to be modified, and subtract your actual waistline size, and you will know that most jeans are missing.

2. Carefully disassemble the waist. According to the size of the pants, the extra parts can be put into the sides of the pants and sewn more accordingly.

4, add straps to transform the style: make two straps with the color of pants and sew them on the waistband. 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.
