Two pencils, 6B and 3H. I started with the bust and moved down the left side to where the hand is lifting the dress. I then followed the sweep of the dress back up almost to the where the other arm should be. I then swooped across the waist and moved over to the right shoulder to bring the other arm down to meet the sweep of the dress. After that I filled in the rest. I thought to maybe post it with just the light lines but then decided I needed some bold ones. I sparingly contoured certain darker areas and called it good.
