Why should I know my sizes?
Maybe you’re buying a bra for the first time. Or you’ve been wearing the same size for a long time.
Researches tell us that many women wear the wrong-sized bra. It’s no luxury to get into the matter of bra sizing a bit yourself.

Remember that sizes can be very close.
A slight change in your measurement could mean a whole new bra size.
Exactly how to measure yourself?
Ask someone to give you a hand if you like.
- stand for a mirror
- measure on bare skin or wear a bra without padding
- ask someone to help if you like it
- write down the measurements
Your underbust and bust size measurements determine your bra size.
That’s all you need.
Well, there is of course a calculator or bra size chart you’ll need to find out your best bra size.

Will my bra size change over time?
Some of us might wear the same bra size as we did 20 years ago. Others might need many different sizes in their lives.
Different causes may change our bra size during life.
Are you in between two possible bra sizes? If this is the case, it might be difficult to choose your best bra size.
I do advise trying also your possible sister size. Remember that different brands may have a different fit also.
