Breast Beauty;Beauty Subjective Assessment;3D Anthropometric Measurements;Regression Analysis
Abstract
This study aimed to explore the relationship between breast shape measurements and breast beauty
assessment. Breast Beauty Subjective Assessment System (BBSAS) was developed to evaluate the beauty
of breasts. 75 female subjects aged 20-39 years were selected for assessment from the anthropometric
database of BIFT-Aimer Human Engineering Research Centre. 43 females working in intimate apparel
design were chosen as judges to answer a five-scale questionnaire using the BBSAS. 66 detailed
measurements especially related to the breast region were also taken for investigation. Data analysis
results indicated that the breast beauty score was highly correlated with breast side view profile and
breast erectness. Beautiful breasts selected by judges had the following common characteristics: the
ratio of bust height to whole body height was 0.71; a triangle was constructed by front neck point, right
bust point and left bust point was an isosceles triangle with the top angle less than 60°. The regression
equation to predict the breast beauty scale was obtained based on key breast measurements. This study
provides a new knowledge on relationship between the breast shape and breast beauty, as well as some
useful guidelines for bra design.
