Convert your size in four steps

  1. Start from your best French size Measure underbust in centimetres or use a French bra that already fits.
  2. Remove 15 and translate the band Subtract 15 to recover the EU band, then convert that number to the closest US band shown in the chart.
  3. Use sister sizes for fine-tuning If the US band feels off, go up or down one band and adjust the cup with a sister size.
  4. Check the fit in US styles US bras may use different fabrics or wires—try nearby sizes before removing tags.

  • Soma
  • Bare Necessities
  • Victoria's Secret

ThirdLove, Soma, and other US-focused labels print inch-based bands by default—use your converted size at checkout.

Global marketplaces

  • Amazon FR
  • Amazon US
  • Net-a-Porter
  • Zalando

Amazon, Net-a-Porter, and cross-border boutiques often list FR, EU, and US columns—confirm the US column before purchasing.

Fit tips after converting

  • Keep the EU band handy as a mid-step when you have to troubleshoot sizing charts.

  • Record both your FR origin size and converted US size to make reorders simple.

French to US conversion FAQ

How do I change a French band to a US band?

Subtract 15 from the French number to find the EU band, then convert that EU band to the closest US inch size.

What happens to French cup letters in US sizing?

France mirrors EU cups, so after subtracting the band you may need to add US double letters like DD and DDD/F.

Do I need to alter the fit after converting?

Start with the converted size. Only adjust the band if you intentionally want a firmer or looser fit, and offset the cup with a sister size.

Where can I shop once I have the US size?

Major US retailers such as Bare Necessities, Soma, and Nordstrom carry a wide range of sizes and ship internationally.
