Why I believe in a well-fitted bra for everyone
We keep reading about the high percentages of women who wear the wrong bra size (varying from 60 to 80%).
I always thought these percentages to be a bit high.
But after measuring myself and other women, I found out that many women still wear the wrong bra (including me).
Of the first four women I measured, three were not wearing the right bra. They knew it, felt it, and saw their ill-fitted bra in the mirror. These women had different body and bra sizes, from AA to D+ cups.
Feeling and touching your bra all day long doesn’t give you confidence. This is uncomfortable and irritating for sure.

Wearing a wrong-sized bra will surely NOT make you happy 😐
Why do we hold on to a badly fitted bra?
- we wear this bra size for many years now, never really wondering if the size is still the right one
- we never had a proper bra size in our lives before, we are still accepting this
- our bodies and breasts have changed (weight changes, childbirth, operation,
etc. ), but we haven’t checked our bra sizes - we know the bra isn’t right, but we don’t take the time to measure ourselves or get a bra fitting
- someone else measured our bra size, and we keep it, although we don’t feel happy with the bra

Measuring yourself
Under Armour HeatGear Mid Padless Sports Bra | See Amazon
Measuring yourself is not difficult, it may take no more than 10 or 15 minutes.
First, you measure your underbust and bust size. So that’s two measurements.
Secondly, you’ll compare your measurements in a bra size chart or bra size calculator.
Voila, that’s it.
Measuring tips
- My advice is to measure a couple of times and write down the outcomes. Only a slight difference in your measurements could mean you would fit another bra size.
- Don’t let this scare you! You need to find out if you’re just in between two bra sizes. It could mean you would fit two different bra sizes, and they both fit you just fine.
- For example. Your bra size is 40D. Your band size is however close to 38 as well. You might fit 40D, but you might also try 38DD/E.
- When you go up or down a band size, your cup size volume will change too. If you want to keep the same cup size, but need another band size? Just go down or up a cup size as well to keep the same cup volume.
