About this conversion
A US 40B converts to a France 105B. 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 France 105B is out of stock, the sister sizes above fit almost identically because they share the same cup volume.
