How French Bra Sizing Works

French bra sizing uses a unique numbering system where you add 15 centimeters to your underbust measurement. For example, a 75cm underbust equals a French band size 90. Common French band sizes are 85, 90, 95, 100, 105, 110, 115. This +15cm system is unique to France and occasionally causes confusion for international shoppers.

French cup sizing follows standard EU letter conventions: A through H and beyond, with no double letters. A French 90C is roughly equivalent to a EU 75C and a US 34C. The key distinction is the band number — French sizing always looks "larger" than EU sizing for the same body because of the +15cm convention.

France is home to some of the world's most prestigious lingerie houses: Simone Pérèle, Aubade, Chantelle, Lise Charmel, and Empreinte. These brands are known for exquisite lacework, luxurious materials, and artisanal craftsmanship. French lingerie emphasizes elegance and femininity alongside technical fit engineering.

When shopping at Galeries Lafayette, Printemps, or Etam stores in France, sizes are displayed in French format. If you normally wear a US 34C, look for a French 90C. Most premium French brands also include EU and UK equivalent sizes on their tags. For online shopping, always check the brand's individual conversion chart — luxury brands may have slightly different cup scaling.
