10 signs you're wearing the wrong bra size

Studies have shown that around 80% of women wear the wrong bra size. Women with average bust sizes usually believe that 75B is a one size fits all. This myth is responsible for 75B being the most commonly sold size in lingerie stores. Because a woman's body is constantly changing, especially during pregnancy and breastfeeding, every woman should take her measurements before purchasing new underwear. If you forgot to take measurements before buying or simply lack the necessary knowledge, you don't have to worry. The wonderful lingerie experts in our BonBon Lingerie stores will be happy to help you.


  1. The back of the bra is not at the same level as the front

The frame and back band of the bra should be at the same height - i.e.H they should form a horizontal line. This common mistake is easy to spot with the help of a mirror. If the back band is too high, you should loosen the hook-and-eye closure and bra straps. If this tip doesn't work, you may want to try on a bra with a smaller strap size. Also remember to choose a bra that fits perfectly when closed at the outermost hook, as the bra will become looser over time. This way you can choose the next hook over time so that the bra continues to fit like a glove.

  1. Overflowing cups

The underwires of the bra must fit perfectly around the breasts. If parts of the breast protrude from the sides or over the edge of the cup, the cup size is too small and the "double breast effect" occurs.


  1. The fabric of the bra is wrinkled and the cups look sunken

You have chosen a cup size that is too large.


  1. The bra band is too loose

The band of the bra must fit tightly to the body. If you can pull the bra band 5 cm away from your body at the back, the bra is one size too big. Try tightening the band of the bra using the hook-and-eye closure at the back, or try a smaller bra.


  1. The bra leaves marks on the skin

If your bra leaves marks on your skin after wearing it for a long time, it is too small. Yes, the bra needs to fit snugly on the body, but not painfully tight.


  1. The bra straps hurt

If your bra straps are causing you pain, try loosening them. If this doesn't make the pain go away, the problem could be that the bra's cup or band size is too small. We recommend that you first try on a bra with a larger cup size, and if that doesn't help, choose a bra with wider straps.

  1. The bra pinches your armpits

This is a sign that you need a larger cup size.


  1. The underwires of the bra protrude from the fabric

This happens when the cup size of the bra is too small.


  1. The center bar of the bra is curved

If the center band of the bra does not rest directly on the skin, the cup size is too small.


  1. The bra needs to be adjusted throughout the day

The right bra shouldn't require adjustment throughout the day, even if you lead a very active lifestyle. If your bra rides up when you lift your arms or you feel like you have to adjust your bra throughout the day, it's the wrong size.



Measuring your bra size is easier than you might think! You just have to believe the tape measure and say goodbye to the belief that you will be the same size your whole life.


Once you find your current bra size, purchasing underwear online becomes much easier. Not to mention how grateful your partner will be if you give him or her a hint about your bra size before an upcoming date like your birthday. Let's get to the point:


  1. Take a tape measure and measure around your torso directly under your bust (where the bra band would normally sit). Ideally, someone will help you with this. You will get the best result if your arms hang down in a relaxed manner. Make sure you don't hold your breath while doing this. The tape measure should lie horizontally on both the back and front and be in contact with the skin. Once you have determined your upper body measurement, you can use the table below to determine your band size:


63-67 cm corresponds to band size 65

68-72 cm corresponds to band size 70

73-77 cm corresponds to band size 75

78-82 cm corresponds to band size 80

83-87 cm is band size 85

88-92 cm is band size 90

93-97 cm is the band size 95

98-102 cm is the band size 100

  1. Take the measuring tape and wrap it around the fullest part of your breast - at the level of the nipples. The next step is to subtract the band size from the bust size. The result is your cup size. Once you have determined your chest circumference, you can use the following table to determine your cup size:


10-12 cm corresponds to cup size AA

12-13 cm corresponds to cup size A

13-15 cm is cup size B

15-17 cm is cup size C

18-20 cm is the cup size D

20-22 cm is the cup size DD

23-25 ​​cm is cup size E

26-28 cm is the cup size F

Combine the band size with the cup size and you have the result!


Did you know that the cup and band size of a bra are linked? This means that if you choose a larger band size, you will have to choose a smaller cup size. And if you choose a larger cup size, you will need to choose a smaller band size.


Different bra sizes can be the same in terms of volume, i.e.H a bra size 70C can fit just as well as a 75B or 80A. Which size is best depends on the bra model itself.



Women tend to buy clothes in a size that they would like. This should motivate us to lose weight and reach our ideal weight. However, this often only reinforces inferiority complexes and the feeling of failure. A bra should always be exactly the right size to fulfill its function: to support the breasts!


A bra in the wrong size not only looks unsightly, but can also be harmful to your health. Bras that are too small or too large can cause health problems that at first glance might not be attributed to the wrong size:


  1. Irritated skin and pain in the chest area

The reason for this could be a bra that is too small or a bra that has been worn for too long. Typically, the lifespan of a bra depends on the woman's size; Curvy women should buy a new bra every 6-9 months, slim women about every 18 months. A bra has exceeded its lifespan when the fabric covering the underwire has visibly thinned and begins to irritate the delicate skin under the breast. A bra that is too worn out will no longer support the breast as effectively as it did in the beginning.


  1. Pain in the ribs, neck and back area

When a bra fails to do its primary job of supporting the breasts, the rest of the body must take on the burden. Different women use different muscle groups to carry the extra load, but the result is still the same: muscle tension and discomfort.


  1. Excessive sweating and overheating

If the bra straps press into the skin and the bra cups feel too tight, your body will sweat and can overheat. When it gets hot outside, it's important to pay attention to the type of bra you wear. This means you should choose a breathable bra in the warm months.


  1. Shortness of breath

Active women who wear a bra that is too tight may suffer from shortness of breath. A bra that is too small restricts freedom of movement in the upper body, resulting in rapid, shallow breathing. This impaired oxygen consumption ultimately affects your entire organ system.


  1. Headache

When your bra fits incorrectly and doesn't adequately support your breasts, your upper body muscles are forced to work extra hard. When these muscles are under intense pressure for a long period of time, it can cause headaches.
