Harper Wilde to Freya bra size

The short answer

Harper Wilde 34D is Freya 34D by the two brands' own charts.

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

Every Harper Wilde size read across to Freya. US sizes on the left, UK 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 Freya chart. Read from the two charts only; no formula and no averaging.
