Short Answer
Overview
The letters found in bra sizes, such as A, B, C, and D, represent the cup size of the garment. This designation indicates the volume of the cup relative to the band size, which is measured in inches or centimeters around the torso. The letter corresponds to the difference between the bust measurement at the fullest point and the underbust measurement. As the letter progresses alphabetically, the volume of the cup increases, though this progression is not linear across all sizing systems.
History / Background
Modern bra sizing systems originated in the 1930s when manufacturers began standardizing measurements to improve fit. Prior to this era, lingerie was often sized simply as small, medium, or large. The introduction of cup letters is frequently attributed to the Warners Company, which began incorporating alphabetic cup sizes in 1937. Over the decades, various regions developed their own standards, leading to differences between US, UK, EU, and Australian sizing charts, though the fundamental concept of letter-based volume remains consistent.
Importance and Impact
Accurate interpretation of bra size letters is crucial for physical comfort and health. Ill-fitting lingerie can cause back pain, shoulder grooving, and skin irritation. Proper sizing ensures that the breast tissue is adequately supported without constriction. Furthermore, standardized letters allow consumers to communicate their needs across different brands, although variations still exist. The system impacts the global lingerie industry by dictating manufacturing standards and inventory management.
Why It Matters
For the modern consumer, understanding what the letters mean reduces the frustration of shopping for lingerie. Many individuals wear the incorrect size due to misconceptions about what specific letters represent. Knowledge of cup volume relative to band size empowers shoppers to find better fits online and in stores. This understanding also helps in navigating sister sizing, where a different combination of band and letter provides the same cup volume, expanding options when exact sizes are unavailable.
