AB - <p style="text-align: justify;">Breast measurement presents a complex challenge in the design of sports bras, particularly for adolescent
girls whose bodies are rapidly changing. This study aimed to explore breast anthropometry among
adolescents. A survey involving 23 girls aged 10 to 14 assessed their understanding of bra-related
problems. In comparison, a wear trial with 7 girls sized 30AA to 32A evaluated their preferences
through five bra conditions, 3D scanning and questionnaires. The study revealed a significant knowledge
gap, with only 8.7% having had a bra fitting and less than half knowing how to determine their bra
size. Notably, the upper bust measurement was significantly correlated with the level of “coolness”
($r=−0.395$ and $p = 0.038$), and the under bust measurement was correlated with the level of “comfort” $(r = −0.441$ and $p = 0.019).$ The findings suggest a need for breathable fabrics in the upper bust
while a preference for a stretchable underband to accommodate body growth. These results highlight
the need to design sports bras tailored to the unique needs of adolescent girls, providing designers
with critical insights into the necessary features and dimensions for optimal comfort during physical
activity.</p>
