Upper Body Proportion: For women who may not be genetically blessed in the lower half, a robust bustline provides a crucial sense of bodily proportion and balance. Men who appreciate this understand that a large bosom can make a woman’s waist look smaller and give her an attractive, top-heavy silhouette. It creates a visually pleasing contrast, especially when the woman has broader shoulders or a slimmer lower body, proving that attractiveness is highly dependent on how body parts harmonize.
