About this conversion

A UK 34G converts to a AU/NZ 12G. Bra sizes have two parts — the band (number) and the cup (letter) — and both are labelled differently across regions, which is why the same bra carries a different size in each country. Always check the brand's own size guide too, as cup grading varies between manufacturers.

If AU/NZ 12G is out of stock, the sister sizes above fit almost identically because they share the same cup volume.
