Shopping for bras in France

French bands add 15 to the EU number: an EU 75 is a FR 90. Cup letters match the EU ladder. French brands cut elegant, slightly shallow cups with refined finishing, so projected shapes often need a cup up from their converted size.

Chantelle, Simone Pérèle and Aubade publish reliable size charts; trust the centimeter measurement over the converted label when the two disagree.

Brands you will commonly see: Chantelle, Simone Pérèle, Aubade, Etam.

How France writes a bra size

France follows the French convention of adding 15 to the European band number, so a bra sold as an EU 75 is printed 90 here. This is the single most misread number on any label, because an 85 tag could belong to either system.

Cups use the same single European letters, so only the number moves between the two conventions.

Sizes are written band first, then cup, as in 90E.

Every row is one body. The FR column is what the label prints; the others are what the same bra is called elsewhere, which is what you need when a brand ships from abroad.

Frequently asked questions

France primarily uses FR sizing conventions in mainstream retail, though imported brands can carry other systems' labels. The calculator above highlights your FR size and shows all 7 systems for imports.

Which bra brands are common in France?

Commonly available names include Chantelle, Simone Pérèle, Aubade, Etam. Local availability shifts, and each brand's own centimeter chart beats any converted label when they disagree.

What is a US 34DD in France sizing?

A US 34DD is a 90E in France. The same bra is a UK 34DD and an EU 75E, because the cup ladders diverge after D.

Do I add inches to my underbust measurement in France?

No. The old habit of adding four or five inches was written for non-stretch fabric and produces a band about two sizes too loose on a modern elastic one. Measure snug and level, and use that number directly, whichever system the label uses.
