Mistakes Women Make When Choosing Bra Size

The right bra size can make all the difference; as told earlier, wearing the wrong bra size can cause serious back pain, breast pain, poor posture, and even neck and shoulder problems.

Wrong Size

The most common mistake women make when it comes to their bra size is choosing the wrong size of bra. Many women don’t realize that their bra size changes with each pregnancy.

This can cause women to wear a smaller or larger cup size which can lead to wearing a bra that doesn’t fit properly or shows through clothes.

Bra Fitting

Another common mistake women make when it comes to their bra size is buying online without trying on the bra before buying it.

Bra fittings are not only important for finding the right fit but also for ensuring that your breasts stay in place throughout the day, be it during office hours or during exercise.

How To Measure The Bra Size?

Measuring the bra size might be confusing if you don’t know how to do it right. So, let’s discuss this further.

How To Measure Bra Size? 
How to measure the bra size? 

Measure the Underbust Area

To find out your bra size, the first thing you need to do is measure your underbust area in inches. Assuming your underbust measurement is an odd number, you should choose the next even number as your band measure.

Take the Measurement of the Bust Area

The next step would be to take measurements of the bust area. 

Let’s say your underbust measurement is 36 inches, and your bust is 38 inches. You can determine your cup size by comparing the measurements of your underbust and bust area.

Find the Right Fit

With each 1-inch difference in your bust measurement, you’ll go for bigger cup size. A 1-inch difference means you’ll fit in 36A bra size, while a 2-inch difference means 36B bra will be your right fit.


  • Buying the right-size bra is no easy task because not all women are aware of how to take the measurements.
  • It’s important to note that the wrong size can cause shoulder and back pain. Your body shape also gets spoiled.
  • Since the sizes differ from manufacturer to manufacturer and country to country, you should always read the measurement table carefully. 
  • If we look at the bra sizes 36A and 36AA, there’s not much difference. The band size remains the same, while the cup size of 36A is bigger than 36AA.
