The Complete Triumph Bra Fitting Guide
The Complete Triumph Bra Fitting Guide
Fit Is Everything
Since 1886, Triumph has been dedicated to one simple belief: every woman deserves a bra that fits perfectly. Founded in Germany, Triumph has grown into one of the world's most trusted lingerie brands — and at the heart of that trust is an unwavering commitment to fit, comfort, and quality.
Studies suggest that up to 80% of women are wearing the wrong bra size. The consequences go beyond discomfort: a poorly fitting bra can affect posture, confidence, and even long-term wellbeing. That's why we've created this complete fitting guide — to give you everything you need to find a bra that feels as good as it looks.
Whether you're buying your first bra, returning after a life change like pregnancy or weight loss, or simply curious whether your current size is still right, this guide is your starting point. We'll walk you through how to measure yourself at home, how to read our size charts, how to identify and fix common fit problems, and how to decode the terminology that makes bra shopping so confusing. Every section links to a dedicated resource so you can go as deep as you need.
Your body changes — and your bra size can too. We recommend re-measuring every 12 months or after any significant body change. A great fit isn't a one-time achievement; it's an ongoing relationship between you and your bra. Let Triumph's 140 years of expertise guide you there.
Find Your Size Now →Step 1: How to Measure Yourself
Getting an accurate measurement is the foundation of a great bra fit. All you need is a soft measuring tape and a few minutes. You'll take two key measurements: your band size (around your ribcage, just below the bust) and your bust size (around the fullest part of your chest). The difference between these two numbers determines your cup size.
It sounds simple — and it is, once you know what to look for. Common mistakes include measuring too loosely, wearing a padded bra while measuring, or rounding to the wrong number. Our Bra Size Calculator walks you through the entire process with clear instructions and a step-by-step video so you get it right first time.

Step 2: Read Our Size Charts
Bra sizing is not universal. A 34B in one brand may fit very differently in another, and different brands and regions use different conventions. Triumph's size charts translate your measurements into the correct size across our full US size range.
Our charts also cover sister sizes — alternative size combinations that offer the same cup volume with a different band length. Understanding sister sizes gives you more flexibility when shopping and helps you find the best fit even when your exact size is out of stock.
Step 3: Use Our Bra Size Calculator
Prefer a faster route? Our bra size calculator takes your measurements and instantly recommends your Triumph size. Simply enter your band and bust measurements and we'll do the math for you — including cup size, sister sizes, and style recommendations based on your result.
The calculator is the quickest way to go from measurements to a confident size recommendation, and it's a great tool to revisit whenever your size might have changed.

Even when you know your size, fit issues can still arise — especially when trying a new style or brand. The four most common problems are a band that rides up at the back, cups that overflow at the top, straps that dig into the shoulders, and a gap between the cup and the breast. Each of these has a clear cause and a straightforward solution.
Our Perfect Fit Tips page breaks down each scenario in detail: what the problem looks like, why it happens, and exactly what to adjust. If your bra doesn't feel right, the answer is almost always a simple size or style tweak rather than a fundamental incompatibility.
Step 5: Learn the Language of Bras
Balconette, demi cup, underwire, minimizer, racerback — bra terminology can feel like a foreign language. Understanding what these terms mean makes it much easier to shop with confidence and choose styles that suit your body and lifestyle.
Our Triumph Bra Glossary defines 25+ common bra terms in plain English, with links to shop each style directly. Whether you're new to bra shopping or just want to brush up on the vocabulary, the glossary is a handy reference to bookmark.

Step 6: Care for Your Bras
Once you've found your perfect fit, the right care keeps your bras supportive and looking their best for far longer. How you wash, dry, and store a bra has a big impact on how long it holds its shape and elasticity.
Our complete care guide covers hand and machine washing, safe drying, smart storage, and special care for lace, underwire, and sports bras.
Step 7: Shop by Fit Need
Once you know your size and understand the styles available, the final step is finding the right bra for your specific needs. Whether you're looking for everyday comfort, a smooth look under fitted clothing, extra support for a larger bust, or a special occasion style, Triumph has a bra designed for you.
