Fit

Does Berlei run small or big?

1Band

Berlei bands run firm across Australian bands 30–46: if you sit between bands, take the larger band with the same cup volume (a sister size).

2Cup

Berlei cups grade true to the measured difference from A to H: a gap or overflow in the measured letter is a shape signal, so change the cut before the size.

3Wire & straps

Berlei wires are average width for the Australian system. Straps: Wide on sport.
