Italian bra bands use a small-number scale from 0 to 8 rather than inches or centimeters — a US 34 band (EU 75) is an Italian 3. Cup letters follow the EU pattern, matching the US only through D.
Italian band sizing is the most compressed of any system in this chart: instead of inches (US/UK) or centimeters (EU), it counts up from 0 in single steps — 0 for the smallest band in this table (US 28 / EU 60) through 8 for the largest (US 44 / EU 100). Each Italian number lines up with one specific EU/US band, so it's a direct lookup rather than a formula.
Cup letters in Italian sizing track the EU sequence, so the same divergence from the US applies: a US DD is an Italian E, a US DDD is an Italian F. A, B, C, and D read the same across US, EU, and Italian sizing.

Cup letters match through D; above D the systems diverge, which is why the cup half of this chart is a lookup, never a formula.
A US 34 band is an Italian 3 (the EU 75 equivalent).
It counts up in whole numbers from 0, with each number matched to one specific US/UK inch band and EU centimeter band — there’s no formula, just a fixed lookup table.
Only through D. Above that, Italian follows the EU sequence, so a US DD is an Italian E and a US DDD is an Italian F, the same as the US-to-EU conversion.
