About Bra Size Calculation

A bra size calculator helps determine the correct bra size using two key measurements: the underbust (band size) and overbust (used to calculate cup size).

•How It Works

The calculator uses a standard method to determine bra size:

–Band size is based on the underbust measurement.
–Cup size is calculated from the difference between overbust and underbust measurements.
–The difference determines cup size (1" = A, 2" = B, etc.).

•Customization Options

The calculator's appearance can be customized using CSS variables:

–--uch-accent: Main accent color
–--uch-bg: Background color
–--uch-text: Text color
