Fit

Does PrimaDonna run small or big?

1Band

PrimaDonna bands run firm across EU bands 70–110: if you sit between bands, take the larger band with the same cup volume (a sister size).

2Cup

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

3Wire & straps

PrimaDonna wires are average width for the EU system. Straps: Wide.
