I experience that a lot of women never really take time to have a proper look at their bra when it’s not comfortable. Or maybe we do notice, but not take further action on that. That’s a shame.

How come many women do not take action? Even when they know that their bra isn’t right anymore?

Well. It’s not that hard to go along with a bra that no longer supports you. Or never has supported you in the first place. It’s only human to go along with something that isn’t right for you, like a bad-fitted bra.

How often does my bra size change?

There are many causes that may change the size and shape of our breasts. Fluctuations in weight, hormones, pregnancy, and aging will have some impact.

Therefore you might need a different bra size more than once in your life.

Do realize that your bra needs to be replaced by a new one at some point. A bra that is worn-out or has lost too much of its elastic fiber can never be right anymore.

  • how does my bra look in the mirror, take some time to have a look at yourself

Only 10 minutes of your time can be enough. Enough anyway to take the first step.
