To make pants tight (I have done it a few times in the past) you take them and turn them inside out. Then
you take the inseams and pinch off how much you want to sew in. Then take the pinched-in inseam and
sew it approximately the length of the thigh vent (if there is one, if not then about 1.5 ft of inseam) Turn
the back to righside-in and then you have skinny snowpants.
