I believe in a well-fitted bra for every woman!

A bra in the wrong size doesn’t make you feel good. No, not at all.

Feeling and touching the bra all day long doesn’t give you confidence and will not make you feel sexy.

Of course, every woman (and girl) should be wearing a well-fitting bra.

In reality, a lot of women do NOT wear the right bra size.

What does my calculator do?

I designed a calculator for women and girls to use. Starting from AAA cups to larger cups D and up

  • when playing a bit with the measurements your bra size may change easily
  • that’s how close bra sizes can be!
  • it may well be that you might fit two different bra sizes and both may fit you fine
  • different brands may have a different fit
  • find out your true bra size or sizes

How come we end up wearing a wrong sized bra?

Our body sizes may change during life,
and so may our bra size

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 indeed still wear the wrong bra (including me).

Stylish fashion for the plus-sized woman shop

From the first four women I measured, three of them were not wearing the right bra.

They knew it, they felt it, and saw their bad-fitted bra in the mirror. These women all had different body and bra sizes, from AA to D+ cups.

Reasons why we stick to the wrong bra

Wearing a wrong-sized bra will surely
NOT make you happy

Why do we hold on to a bad-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, still accepting this
  • our body 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

Quick guide to measuring your bra size

measuring your bra size and use our bra size calculator

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 in a 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! It’s important for you 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 38E.
  • 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.
