It is often necessary to alter men's clothing by removing and adjusting various seamlines. For cargo pants, the waist and length of the pants can be altered for a better fit. When altering pants, it is always a good idea to verify the height or waist size of the customer before beginning the tailoring process.
Discuss with the customer what adjustments are required.
Measure the customer to verify the irregularity and mark any changes to the pants with chalk.
Pin the cuffs to the correct hemmed length with the customer wearing the pants.
Remove the seams with a seam ripper. For the waist, remove the back crotch seam. For the length, remove the current hem.
Adjust the seams to the requested size and re-sew the pants.
Ask the customer to try on the cargo pants before leaving to verify that the alterations provide a good fit.
