What do we mean by inner-tailored waistband?

The inner-tailored waistband of pants is the finish given to pants inside.

There are differing levels of quality: from pre-produced to personalised, or even fully hand made for each garment. Messori uses a high-quality personalised inner-waistband which also has an interesting innovative touch: a narrow rubber strip has been incorporated into the edge of the waistband to prevent shirts from slipping out of the pants, especially due to movement.
