How Italian Bra Sizing Works
Italian bra sizing uses a numbered system for bands that is unique to Italy: size 1 = US/UK 30, size 2 = US/UK 32, size 3 = US/UK 34, size 4 = US/UK 36, size 5 = US/UK 38, and so on. The sizing is linear — just add 1 to go up one band size. Cup sizes follow EU conventions (A, B, C, D, E, F), making Italian sizing a blend of a unique band system and standard EU cup progression.
An Italian size 4C is equivalent to a EU 80C, a French 95C, and a US/UK 36C. The conversion rule: Italian band number × 2 + 22 gives the approximate underbust in inches. Conversely, (US band − 22) / 2 gives the approximate Italian band number.
Italy produces some of the world's most iconic lingerie brands: La Perla (luxury silk and lace — the gold standard of Italian lingerie), Intimissimi (accessible luxury with stores throughout Italy), Calzedonia (known for quality basics), and Verdissima. Italian design sensibilities prioritize beautiful fabrics, flattering cuts, and a balance of comfort with sensuality.
When shopping in Italy at La Rinascente, Coin, or OVS department stores, sizes are displayed in Italian format. Intimissimi stores are found in nearly every Italian city and use Italian sizing. For international shoppers, note that Italian cuts often run slightly smaller in the cup than US/UK brands — sister-sizing up one cup is sometimes needed for the ideal fit.
