How to Draw a Woman's Pants Wardrobe
Draw a great pair of skinny jeans.
Draw the lower half of your figure using a front grounded pose. Add the center front line and waistline of the pants. For skinny jeans, draw lines for the side seams and inseams by following the shape of the legs exactly.
Skinny jeans need to be tight. If one leg is bent at all, add in a few bendy lines to show the fabric bunching. These lines communicate how tight the jeans are.
Draw the hem of the jeans by wrapping the hemline around the ankle. Add in the topstitching lines following the hemline. Skinny jeans can be different lengths. Some styles end right below the ankle, and some are very long and bunch or gather below the ankle at the top of the foot.
Draw the waistband, including the center front button, belt loops, topstitching, and pockets. Draw the front fly by using at least two rows of topstitching in the J shape, starting at the waistband and going down the center front line.
