About this conversion
A US 42B converts to a AU/NZ 20B. 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 20B is out of stock, the sister sizes above fit almost identically because they share the same cup volume.
