The tool assists lactating individuals in determining appropriate brassiere dimensions to accommodate changes in breast size during pregnancy and breastfeeding. It typically requires measurements of chest circumference and bust size, utilizing these figures to estimate the correct band and cup size. The estimation factors in considerations unique to lactation, such as increased breast volume and potential fluctuations in size due to milk production.
Properly fitted support garments are important during this physiological stage. They can provide comfort, alleviate back pain associated with increased breast weight, and facilitate discreet nursing. Historically, individuals often relied on manual measurements and trial-and-error methods to find suitable undergarments. The advent of these tools aims to provide a more accurate and convenient method, potentially reducing discomfort and promoting a more positive breastfeeding experience.
