First, Grace combined the clues from the color of her Skin, Hair and Eyes with her Body Frame Size. These body clues tell her that her overall scale is small/medium. Since the pattern covers her whole body, she should look for prints with this scale size. If the print was in one area, she would look at her Body Proportions to adjust that scale up or down. Because she’s short between her bust/waist, she would decrease the scale to small. On the other hand, if the print was just between her waist/crotch, she would increase the scale to medium.
