Intimissimi to PrimaDonna bra size

The short answer

Intimissimi 34D is PrimaDonna 75D by the two brands' own charts.

Cups are counted along each brand's own letter order, and the band is carried across unchanged.

Every Intimissimi size read across to PrimaDonna. US sizes on the left, EU on the right.

Neither chart publishes the body each size is built for, so the rows line up the labels. Tinted rows change label or sit between two sizes. 1 sizes have no counterpart on the PrimaDonna chart. Read from the two charts only; no formula and no averaging.
