About this conversion

A US 46DDD converts to a UK 46E. 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 UK 46E is out of stock, the sister sizes above fit almost identically because they share the same cup volume.
