1. How to properly measure your bra size?

The first step to knowing your exact size is to take your measurements correctly. Arm yourself with a flexible tape measure and follow these steps:

  1. Measure your band: place the tape measure just below your bust, at the level of the rib cage, and note the measurement obtained in centimeters.

  2. Measure your bust: position the tape measure at the level of the nipple tips, without tightening, and note this second measurement.

Then, to calculate your size for a bra, simply subtract these two measurements. This difference will correspond to the cup size that suits you. For example, a difference of 15 cm generally corresponds to a cup B. This will allow you to determine the right size and choose a model perfectly suited to your body shape.

Remember that the French size may vary compared to foreign sizes. It is therefore important to check size correspondences if you are buying abroad or online.

2. Choose the perfect size for impeccable support

It is essential to choose your size accurately to avoid discomfort. Consult a size chart or use an online calculator to confirm your measurements. Make sure that the band size corresponds well to your body shape and that the cup size is suitable for the depth of your bust. An exact size will guarantee you optimal comfort throughout the day.

Don't hesitate to try several sizes and models to find the one that suits you best. Sometimes, a larger or smaller size can make all the difference in terms of comfort and support.

3. Finding the ideal bra model for your body shape

1. The different types of bras

There are a multitude of models to satisfy all desires:

  • The wireless bra for a natural shape and comfort; 

  • The balcony bra for a pretty neckline

  • The push-up bra to enhance a small bust

  • The sports bra for unfailing support in motion;

  • The nursing bra for young moms looking for functional clothing. 

Each model has its specifics, so it is important to know them to choose a bra shape with full knowledge of the facts. Les Petits Imprimés offers a varied selection that will meet your expectations in terms of quality and taste. 

2. Which bra to choose for a large bust?

If you have a large bust, choosing the right bra is important for better support. Opt for models with wide straps and reinforced closures (at least 3 rows of hooks, for example). 


Full-coverage bras provide excellent support and unmatched comfort thanks to the enveloping underwire cups. For those who want a shaping effect, the push-up bra is worth considering. Finally, it is essential to have an effective sports bra for any physical activity, to preserve the health of your bust.


A generous bust requires effective support to avoid back pain. Models with reinforced underwire and quality materials are recommended. At Les Petits Imprimés, you can find pieces specially designed to ensure your comfort throughout the day.

4. Adapting your bra to your outfit for a flawless result

Tired of straps sticking out and cups digging into your cleavage? Choosing the right bra based on your outfit is essential for comfort, support, and aesthetics. Here are some must-have models and their uses:

  • Backless bra: Perfect for dresses and tops with a low back, it provides good support while leaving the back exposed.

  • Invisible bra: Designed with discreet straps and seams, this model is worn under thin or fitted fabrics, such as tight T-shirts or silk blouses. It avoids marks under clothing for a flawless look.

  • Adhesive bra: Strapless and backless, it is perfect for very low-cut outfits or strapless dresses. Be careful, this model is mainly suitable for small to medium busts to maintain good support.

  • Push-up: Ideal for creating a plunging effect under a V-neck dress or a low-cut top. This model lifts and shapes the bust, adding volume and a structured effect.

5. Size mistakes to avoid at all costs

To avoid making an error in size selection, it is important to regularly check your measurements, especially if your weight fluctuates. A bra that is too small can compress the bust and cause pain, while a bra that is too large does not support the bust properly and can lead to embarrassing moments. Don't hesitate to try several sizes to find the best-fitting bra for your body shape.


Here are some signs that your bra is not the right size:

  • The straps slip or leave marks on the shoulders.

  • The band under the bust rides up in the back.

  • The cups are wrinkled or do not fully cover the bust.

A question on your mind? We have the answer!

How do I know if my bra is the right size?

Check that the band under the bust is well-fitted without riding up and that the straps do not leave marks. The cups should fully cover the bust without wrinkles or overflow.

Which bras should I prioritize according to my body type?

For a small bust, opt for a push-up or triangle. A large bust requires a full-coverage model with wide straps for optimal support. Every body type has its ideal models!

Can I wear the same bra under all my outfits?

No, adjust your choice: invisible for fitted clothes, adhesive for strapless dresses, multi-position for backless styles, or push-up for plunging necklines. The ideal: a variety according to your needs.
