Determining your bra size is an intimate ritual, a moment of self-care. It revolves around two simple measurements: your underwidth (the circumference directly under your breasts) and your breast size (measured across the fullest part). The difference reveals your cup size. Measuring this correctly is the first, and most essential, step toward lingerie in which you feel irresistibly feminine.
The Essence of a Perfect Fit
A bra that fits perfectly is the invisible foundation of your outfit and a subtle source of confidence. Finding the right size is more than numbers and letters on a label; it is a moment of connection with your body, a way of embracing your femininity. When you wear lingerie that feels like a second skin, it not only improves your posture and silhouette. It also gives you a sense of luxury and sensuality, from dawn to dusk.

Why the right size is crucial
Surprisingly many women unknowingly wear the wrong bra size. Not only does this cause physical discomfort such as cutting straps, stinging underwires or a back band creeping up, but it also detracts from your appearance. A wrong fit can disrupt the line of a beautiful dress or make you feel insecure in a simple top. It’s all about that perfect harmony between fabric and skin.
“A perfectly fitting bra doesn’t feel like an obligation, but an extension of your femininity. It is the secret weapon that improves your posture and enhances your appearance.”
The impact of good lingerie is more than what you see. It’s a psychological boost that helps you feel powerful and sensual, even when no one else sees it. Whether you choose a sophisticated lace set for a date night, a practical model for every day, or a bold design for a moment of self-love; the foundation is always the perfect fit.
This guide is your personal invitation to take a fresh, loving look at your body and your lingerie. We dive into the secrets of sizing so that your lingerie not only supports, but inspires you every day and gives you a sense of unparalleled elegance.
Discover how the right size and style can accentuate your natural beauty and give you a sense of freedom and confidence. Your journey to the perfect fit begins here.
The Basis of Support: Measuring Your Girth
Did you know that the band of your bra provides as much as 80% of the support? It’s the silent hero that holds your entire look together. A perfect measurement is the first step to a fit that is not only comfortable, but also gives you an undeniable dose of confidence.
Grab a flexible measuring tape. Bring the tape tightly around your body, directly under your breasts. Right where the underwire or bottom edge of your bra should rest. Make sure the tape is the same height everywhere, both in the front and on your back. A common mistake? Letting the ribbon hang too loose for fear that a tight band will pinch.
Resist that tendency. Instead, the bond should feel firm and connected, like a gentle but supportive embrace. Exhale calmly and completely, then read the measure. The ribbon should be tight enough that it won’t shift, but you should still be able to breathe comfortably with it.
From measurement to measure
Now that you have the number of centimeters, it’s time to convert this to the correct tire size. In the Netherlands and the rest of Europe, we use a fairly logical system. The European standard EN 13402 has provided standardization, which makes it a lot easier for us.
Specifically, you round the measured circumference to the nearest multiple of five. For example, do you measure 78 cm? Then your tire size is 80. Do you come out at 76 cm? Then round down and your size is 75.
Really take some time for this. This is the foundation. A good foundation prevents those typical bra problems, such as a back strap creeping up. That’s a sure sign that your band is too wide and you’re not getting the support you deserve.
A firm, perfect-fitting bra does wonders for your silhouette under a silk blouse for an intimate dinner party, but it also gives you all-day comfort and confidence. It’s that invisible promise of support that lets you focus on shining.
Now that the basics are in place, you’re ready for the next step: determining your cup size. This is where we really get to celebrate the unique shape of your cleavage. As you browse through our collection, from seductive balconette bras to delicate bralettes, remember that the right underwidth is the beginning of everything. It ensures that each piece from JustPleasure not only looks beautiful, but also feels like a dream.
Finding Your Cup Size: More Than Just a Letter
The band size is the foundation; the cup size is the poetry. Here it’s all about the volume and unique shape of your breasts. Think of the cup not as just another letter, but as the perfect envelope that shapes your cleavage and celebrates your feminine silhouette.
Take out the tape measure again. This time place it smoothly over the fullest part of your breasts, which is usually right at the level of your nipples. Pay close attention that the tape runs completely straight and horizontal around your body again. Crucial here: do not compress the breast tissue! The ribbon must rest gently on it, otherwise you will get a wrong measurement.
From numbers to cup size
The secret behind your cup size is a surprisingly simple calculation. You take the bust size you just measured and subtract from that your previously measured bottom size. The difference between those two numbers is the key to your cup size.
Suppose your chest circumference is 94 cm and your lower width was 79 cm (which you rounded to band size 80). The difference is then 15 cm(94 – 79 = 15). This difference is shown in the European size chart for a C cup. So your starting point for the search for the perfect bra is 80C.
Did you know that the average cup size in the Netherlands is usually somewhere between B and D? Lingerie brands respond to this, but of course it is essential that all sizes are well represented.
The process of measuring your undersize – the basis for everything – is actually a small, simple ritual with a big effect on your daily comfort.
Measure, note and round up. That’s it. The table below will help you convert the difference you calculated directly to the correct European cup size.
Cup size determination based on difference
| Difference (in cm) | European Cup Size |
|---|---|
| 10 – 12 cm | AA |
| 12 – 14 cm | A |
| 14 – 16 cm | B |
| 16 – 18 cm | C |
| 18 – 20 cm | D |
| 20 – 22 cm | E |
| 22 – 24 cm | F |
| 24 – 26 cm | G |
| 26 – 28 cm | H |
Remember, this is a great starting point. The final fit also depends on the brand and model of bra you choose.
Your unique form also counts
Your breasts are so much more than a number and a letter. Their unique shape is just as important for the perfect fit. Are your breasts beautifully round, do they have a bit more volume at the bottom (pear-shaped), or is there a slight difference in size? Each shape is beautiful and requires a different type of bra to really come into its own.
- Round breasts: These are already naturally full. Many styles will look great on you, from a seductive balconette bra to a seamless t-shirt bra.
- Pear-shaped breasts: If your breasts are a bit fuller at the bottom, a plunge or push-up bra can work wonders. These styles give a nice elevator and create beautiful cleavage for a night out.
- Asymmetrical breasts: Almost every woman has a slight difference in size. Bras with removable inserts or cups made of flexible stretch lace are ideal for creating a beautiful, even silhouette.
With this knowledge, not only will you find your size, but you can consciously choose styles that best accentuate your natural beauty. Whether you’re looking for something for an intimate evening, your honeymoon or just a moment to yourself, the right bra will make you shine.
The Art of Fitting: Indicators of a Perfect Fit
Your measurements are a wonderful guide, but the mirror reveals the true magic. Trying on a bra is an intimate ritual, a moment when you enter into dialogue with your body and the lingerie. It is more than checking off a checklist; it is feeling, looking and experiencing.

A good fit is an interplay of different elements that must be perfectly balanced. Only then will you experience that feeling of luxury, comfort and unprecedented self-assurance.
The Band: Your Foundation
The band should run low and perfectly horizontal across your back, like an elegant line. Does the band creep up? Then your size is probably too big. This causes you to lose the crucial support that comes as much as 80% from the band.
The band should feel firm, but certainly not squishy. A good rule of thumb is that you can comfortably slip two fingers under it. Always close a new bra on the loosest hook. This allows you to tighten the band as the elasticity decreases a bit over time.
The Brackets and Centerpiece: The Framing
Underwires are meant to frame your breasts, not pierce them. They should rest flat against your chest and follow the full curve of your breast without poking. The center piece, the piece of fabric between the cups, should also rest flat against your breastbone. Is it facing away from your body? Then the cups are probably too small.
A perfectly fitting bra feels like a second skin. The underwire and center piece form a seamless unit with your body, giving you the freedom to move with confidence.
The Cups: Perfectly Filled
The cups should fill your breasts completely without leaving any space. At the same time, your breasts should also not form ‘bubbles’ above them. That ‘quad boob’ effect is a clear sign that the cup size is too small.
A clever trick that every lingerie stylist uses is the “scoop and swoop” technique. After you put the bra on, bend over slightly. Use your hand to gently “scoop” your breast into the cup so that all the breast tissue falls neatly inside the underwire. You’ll be amazed at the difference this makes.
A perfectly fitting bra subtly accentuates your silhouette, whether you’re wearing a silk blouse for an intimate dinner or a cashmere sweater for a moment of self-care. It’s your secret weapon. When the band, underwires and cups are in perfect harmony, you feel it immediately. Browse the sophisticated collection at JustPleasure and find the styles that embrace your unique shape.
Finding Your Size in International Lingerie Brands
The world of luxury lingerie is an international playground full of seduction and craftsmanship. However, an elegant French 85C is not the same as a bold British 32C. Don’t let that confusion keep you from discovering that one gorgeous set from a foreign brand.

With the right knowledge, international shopping becomes an effortless and even fun experience. Think of this as your personal translation guide to the language of lingerie.
Understanding the differences
The main difference is almost always in the tire size.
- France/Spain (FR/ES): To find your French or Spanish size, add 15 cm to your European tire size. So a European 75 becomes a French 90.
- United Kingdom (UK) & United States (US): Here they calculate with inches. A European tire size 75 corresponds to a 34 in the UK and US.
- Cup sizes: From cup D onwards, the differences really begin to stand out. Where we in Europe continue with E, F and G, British brands often use double letters, such as DD, E, F, FF and G.
Converting your size opens the door to a world of breathtaking designs. It gives you the confidence to effortlessly choose that one seductive set from a Parisian atelier or an innovative design from London.

| 70E | 85E | 32DD | 32DD |
| 75F | 90F | 34E | 34DDD/F |

All Your Questions About the Perfect Bra Size Answered
The search for that one, perfectly fitting bra can sometimes raise questions. It’s the details that make the difference between a bra that’s “okay” and one you feel great in. Here we dive into the most frequently asked questions, with the expertise to help you choose your next lingerie piece with confidence.
After all, lingerie is a very personal choice. Whether you are looking for an exciting set for a date night or a comfortable bra for every day, with the right knowledge, you will make choices that truly suit you and celebrate your femininity.
How often should I actually re-measure my bra size?
Your body is not static; it is beautiful and constantly changing. Weight fluctuations, your hormonal cycle or pregnancy all affect your breasts. Therefore, don’t think of determining your bra size as a one-time job, but as an annual moment of self-care.
Schedule a time at least once a year to get the tape measure out again. Notice in between times that your bras are pinching or the band is creeping up? That’s your body’s signal that it’s time for another measurement.
What is a “sister mate” and when does it come in handy?
Sister sizes are one of the best-kept secrets in the lingerie world. They are alternative sizes where the cup volume remains virtually the same, but the circumference size is different.
- Band too tight, but the cup sits perfectly? Go up one band size and down one cup size. For example, a 75C then becomes an 80B.
- Band too loose, but the cup sits perfectly? Go down one band size and up one cup size. In this case, a 75C becomes a 70D.
Knowing your sister sizes gives you much more flexibility when shopping. It opens the door to more brands and styles.
A sister size is like a tip from a good friend; a small adjustment that can make the difference between a good and a perfect fit.
My bra strap creeps up on my back, what does that mean?
A creeping back strap is the clearest signal that your size is too big. The band is responsible for about 80% of your support. If it’s too loose, all the weight ends up on your shoulders, leading to pain and detracting from your silhouette.
The solution is simple: try a smaller size. As the band tightens, you often need a cup size larger to maintain the same volume (there’s that sister size again!). This restores balance and gives your breasts the elevator and comfort they deserve.
The underwire of my bra stings my skin, how do I fix it?
Stinging underwires are a clear sign that the fit is not in harmony with your body. Usually the cause lies with the size or style chosen. If the circumference size is too large, the bra may slide. It may also be that the cup size is too small, causing the underwire to rest on the soft breast tissue.
Experiment with a different size – a sister size, for example – or try a bra style that better suits the shape of your breasts. A perfectly fitting underwire hugs your breast like a work of art without ever causing discomfort.
With these insights, you are all set to discover the lingerie that not only fits, but also makes you feel luxurious and confident. Explore the sophisticated collection at JustPleasure and find the pieces that celebrate your femininity.
