Complete Guide to International Lingerie Size Conversion

Shopping for lingerie online can feel like decoding a secret language—especially when you're staring at a size chart that reads like ancient hieroglyphs. One minute you’re a 34B in the U.S., and the next, you're somehow a 75B in Europe? Yeah, we’ve all been there. Don’t panic! This ultimate guide to international lingerie size conversion breaks down the confusion with real data, easy tips, and a handy conversion table so you can shop with confidence—no guessing required.

Why Lingerie Sizes Vary Around the World

The truth? There’s no universal standard. The U.S., UK, EU, Australia, and even Asian markets use different measuring systems and band calculations. For example, European brands (like Triumph or Aubade) use centimeters for band size, while American labels stick to inches. Plus, sister sizing—where 34B = 36A = 32C in volume—adds another layer of complexity.

A 2022 survey found that over 68% of women wear the wrong bra size, often due to inconsistent labeling across borders. That’s why understanding conversions isn't just helpful—it's essential for comfort and support.

Note: In the UK and some EU countries, DD = E, E = F, and so on. Always check brand-specific charts!

Tips for Accurate Sizing Across Borders

• Measure Yourself: Use a soft tape measure around your ribcage (under bust) and fullest part of your bust. Subtract underbust from bust measurement—each inch equals one cup size.
• Embrace Sister Sizing: If 34C feels tight, try 36B—it’s the same cup volume with a looser band.
• Check Brand Origins: French brands (e.g., Chantelle) tend to run smaller; Japanese labels (like Wacoal) often have petite fits.
• Read Reviews: Sites like ASOS or Nordstrom include customer feedback like “runs small” or “size up for fuller cups.”
