How to Read Lingerie Size Charts Accurately

Let’s be real—figuring out your correct lingerie size can feel like decoding a secret language. One brand says you’re a 34B, another insists you’re a 36C. Sound familiar? You're not alone. In fact, studies show that **up to 80% of women wear the wrong bra size**—and a big reason is misunderstanding how to read lingerie size charts.

As someone who’s reviewed hundreds of brands and helped thousands of readers find their perfect fit, I’m breaking down exactly how to read these charts like a pro. No more guessing. No more discomfort. Just accurate, confidence-boosting results.

Why Lingerie Size Charts Matter

Every brand fits differently. European labels often run smaller than U.S. ones. Some focus on band snugness, others on cup volume. That’s why relying solely on your 'usual' size is risky. A proper size chart gives you the actual measurements each size corresponds to—so you can compare them to your body, not just trust a label.

Here’s a quick comparison of average measurements across top lingerie brands:

*Note: Cup volume increases with band size—even within the same cup letter.*

How to Use a Lingerie Size Chart Correctly

1. **Measure Yourself First** - Band: Wrap the tape around your ribcage, just under the bust. Keep it snug but not tight. - Bust: Measure at the fullest part, keeping the tape parallel to the floor. - Subtract band from bust to estimate cup size (each inch ≈ one cup size).

2. **Check the Brand’s Chart Before Buying** Always go to the brand's official [lingerie size chart](/) page. Don’t assume consistency. For example, a 34D at Natori may fit like a 36C at Cosabella due to cup depth differences.

3. **Look Beyond Numbers** Some brands use vanity sizing or regional standards. European brands like Empreinte often list sizes in EU format (e.g., 80E), which converts to a 34DD in the U.S. Use a conversion tool—but double-check volume.

4. **Read Reviews With Your Size in Mind** If multiple reviewers say “runs small” or “tight band,” size up. Real user feedback complements the [size guide](/) perfectly.

Final Tips for Confidence

- Re-measure every 6 months. Bodies change. - Try multiple sizes when shopping online. Many brands offer free returns. - When in doubt, consult a certified fitter—or use AI fitting tools now offered by sites like ThirdLove and True&Co.

Getting the right fit isn’t just about comfort—it’s about feeling amazing in your skin. Now that you know how to read a lingerie size chart like an expert, you’ll save time, money, and frustration.
