How to Draw a Woman's Pants Wardrobe
Draw sweats with elastic bottoms.
Draw a fashion figure from a side view and give her an elastic waistband. Draw the pant legs, side seams, and inseams of the legs, keeping the pant legs loose and bubbling out a little before being tightened at the calf or ankle.
At the bottom of each pant leg, draw a wide cuff with squiggly vertical lines to show the elastic of the cuff. Add some lines that come up from the cuff to show the fabric bunching slightly.
Add letters going down the leg for a varsity look. The side of the leg is a good place for a long word, like a school or team name.
