How the calculation works
V16 calculation/specification: return prePregnancySize,currentBust,currentHip,garmentType as the maternity-clothing sizing profile; final labelled size must be selected from the exact maternity brand's current chart for garmentType.
Worked example
Example: Pre-pregnancy generic size index = 2; Current bust circumference = 50 cm; Current hip circumference = 98 cm; Garment type = top. Result: Use this measurement profile with the exact current manufacturer, brand or governing-body chart; no universal labelled size is assumed.
Before you decide
The result is only as accurate as the measurements entered. Use the current manufacturer, brand, league or governing-body specification for the final labelled size or rule; those external charts can change and are not treated as universal constants.

Runtime-specific source required. Use the exact current manufacturer, brand, model, regional conversion, league or governing-body chart/rule that applies to the user's actual product or competition; a single static URL would be misleading.
