If you have no soft measuring tape at home you can even print one from the internet. Also, you could use some soft rope and use a ruler to measure the length.

Secondly, decide on your cup size

Ever heard of the fruit method to find your cup size?

Well, it is a funny and simple guideline to get things started.

If your breasts are small you might start off by trying an A cup. But it could as well be you need AAA or AA. Remember that sizes can be very close!

Remember that going up or down a band size will automatically change the cup volume!

For example. You try the bra 34A and feel the band is a bit too tight. The cup size is fine. You should try 36AA in order to have a wider band and to keep the same cup volume. What is my bra sister size?
