A Study on Transformation of The Breast Size, Shape and Volume Properties for Design of Maternity Brassiere

임산부용 브래지어 설계를 위한 유방부 변화에 대하여

This study was performed to provide basic data for design of maternity brassiere. In order to find out transformation of breast size, shape and volume properties during the period of pregnancy, direct measurements of 306 subjects using Martin's anthropometer and indirect measurements using photography were conducted. And also breast surface area, volume and assumed weight using the molding of adhisive sheet are calculated. The results are as follows; 1) Size (breast widths, depths, girths and lengths) of the breast of pregnant woman are gradually increased during pregnancy. But underbust girth is decreased after delivery. 2) Front view of the breast is gradully dropped and widened. 3) Surface area, volume were measured for each stage of pregnancy, and weights of breasts were estimated. The surface area of breast of latter stage of prgnancy was increased 1.7 times comparing with the early stage. 4) Changes of bust girth, breast depth, underbust girth, volume and estimated breast weight during pregnancy should be considered for cup size, cup shape, width and strain of strap, and width of the wings.
