To create the interior of the garment I started with a base color picked up from a light area of her shirt. Using a quick mask I brushed a flat tone on for starters. This does not truly replicate the look of the shirt in the original. I tried using the bright translucent color area caused by the sun but it looked incorrect. For some reason it looked artificial and kind of electric. So I opted to use a slightly darker color.The interior of the collar is multiple layers of cloth and would be darker. I picked up a tone from the shadow side of her shirt to use there.
