Understanding bra sizes

Choosing the perfect bra can sometimes seem like a daunting task, especially when you're between sizes. But did you know that the key lies in understanding measurements and size equivalencies? Knowing your exact size is essential to finding the bra that will give you comfort and support all day long.

How sizes are measured

To determine your bra size, you need to measure two essential elements: your under-chest measurement and your bust measurement. The underbust measurement determines the length of the bra band. As for the cup, this is calculated by taking the difference between the bust measurement and the underbust measurement. For example, if your measurement 1 (bust circumference) is 95 cm and your measurement 2 (underbust circumference) is 80 cm, then 95 - 80 = 15 cm; this corresponds to a C cup.

Variations between brands and countries

It's also important to be aware that sizes can vary between brands and countries. An 85C in France may not correspond exactly to a 34C in the UK or a 75C in continental Europe. These variations can be confusing, but they underline the importance of trying on several models to find the one that fits you perfectly.

Sister size" tip

One tip for those who find themselves between sizes is to use the concept of "sister sizes". If, for example, you usually wear an 85C but it's not available, you can try a 90B or 80D. These so-called "sister sizes" offer a practical alternative without compromising comfort or fit.

The importance of fitting and adjustment

Trying on a bra remains a crucial step in the bra selection process. Always take the time to adjust each model you try on correctly: check that the straps don't slip, that the band doesn't ride up the back and that your breasts are well enveloped by the cups without excessive spilling or wrinkling.

The impact of an ill-fitting bra

Pay particular attention to the fit, as an ill-fitting bra can cause back pain, skin irritation and muscle tension. So it's crucial to invest in models that offer not only style but also ergonomics.

Tips for everyday comfort

Also remember to choose soft, breathable materials like cotton or microfiber to avoid skin irritation. Flat seams also minimize unpleasant rubbing on the sensitive skin around the bust.

Here are a few tips for taking care of your bras:

  • Adjust your straps regularly to maintain a good level of support;
  • Take care to wash your bras by hand or with a protective net if you use a washing machine;
  • Don't hesitate to consult online guides or ask for advice when buying in a specialist store.

Choosing a bra between two sizes

Do you often find yourself between two bra sizes? Don't panic, it's a common situation and there are solutions to help you find the one that's just right for you. The "sister size" trick can be your precious ally in this quest.

Sister size" tip

The "sister size" concept is based on the fact that certain bra sizes are interchangeable. For example, if you usually wear an 85C but need a little more room around the bust, a 90B could be the ideal solution. Similarly, if your back is too large in a 90B, try an 85D for a perfect fit.

Here are a few equivalents to help you understand:

  • An 85C corresponds to a 90B or an 80D.
  • A 90C can be replaced by a 95B or 85D.
  • A 75E could just as easily be replaced by an 80D or a 70F.

The importance of fitting and adjustment

Fitting remains an essential step. Every woman has a unique morphology, and every brand offers slightly different cuts. Take the time to try on several models and brands to discover what suits you best. Don't hesitate to adjust the straps and check that the back band remains horizontal without riding up the back.

Anecdote: a loyal customer confided in us that she had found her happiness by combining the "sister size" trick with bra extenders. By simply adding this accessory, she was able to adapt the length of the back while maintaining the perfect cup size for her bust. It's a handy little trick that can make all the difference!

Taking care of your comfort and health

The impact of an ill-fitting bra should not be underestimated. A bra that's too tight can cause shoulder and back pain, while one that's too loose won't provide the support you need. So it's crucial to pay close attention to these details to ensure your daily comfort.

Taking care of your comfort and health

Choosing a bra isn't just a question of aesthetics or fashion. Above all, it's about your daily well-being. An ill-fitting bra can cause everything from back pain to skin irritation. Have you ever wondered whether your current bra really suits you? Let's take a moment to explore the impact of an ill-fitting bra and tips for ensuring optimum comfort.

The impact of an ill-fitting bra

A bra that doesn't support your breasts properly can affect your posture and cause muscle tension. For example, a back that's too tight can compress your ribs, while a cup that's too small can create painful pressure points. In the long term, these discomforts can even affect your quality of life. To avoid this, it's crucial to know your exact measurements.

Tips for everyday comfort

To ensure perfect support all day long, here are a few simple tips:

  • always adjust the shoulder straps: they should be tight enough to support you without digging into your shoulders.
  • think about an extender: if your back is too tight despite a correct size, use an extender to add a few extra centimetres.
  • Vary styles according to activity: a non-wired bra for relaxing at home, a sports bra for exercise and a more structured version for the office.
  • Choose breathable materials: fabrics such as cotton or technical blends prevent irritation and allow the skin to breathe.

Remember that every woman is unique. What works perfectly for one may not suit another. That's why it's essential to try on different models and sizes until you find the one that fits your shape perfectly and offers you the comfort you need.
