Finding Your Fit

Many women wear the wrong bra size. The standard US fitting method uses two measurements: your band size (underbust) and your cup size (the difference between bust and underbust).

Measuring Tips

For the most accurate results, measure while wearing an unpadded bra. Keep the measuring tape level and snug for the band, but slightly loose over the fullest part of the bust.
