This is a free front trouser sloper pattern for adults with the Y build. This uses the natural waistline. If a waistband depth value is added, the draft will lower so that the top of the waistband would sit at the natural waist level.

There is no ease in this draft and you'll need to add hip ease and waist ease. Although the full ease values will be added, waist and hip ease is not added equally to the front and back patterns. Waist ease is 36% to the front and 64% to the back. Hip is is 40% to the front and 60% to the back.

You can also increase the crotch depth ease, which is set at  0.4" / 1cm by default. 

The circumference of the pant leg at the hem will be calculated using two times the ankle circumference, if a pant leg circumference is not entered.
