Sewing Tip | Sewing for your cup size |

Today, we are looking at a particular measure which allows a blouse or a dress to be properly adjusted which is the cup.

There are two measurements called a cup. The first one that we know well is used to measure and choose the cup of a bra. As for the second, it is used to measure and choose the cup of a garment from a sewing pattern. It is important to note that these are two different measurements and that they do not correspond to the same thing. We must therefore not be mistaken between the two methods.

The bra cup

To choose the right bra, you need the bust measurement, which is the measurement across the fullest part of your bust, and the back measurement, which is the measurement located just under the bust.

The formula is as follows:

Cup = Bust – Back

Once the calculation is done, you will find the measurements below which will give you your cup for a bra in your size.

Cup A: 13cm

Cup B: 15cm

Cup C: 17cm

Cup D: 19cm

Cup E: 21cm

Cup F: 23cm

The sewing pattern cup

We get to the measurement that interests us the most, it is the one that tells us about the cup to know the size for a sewing pattern.

The formula is as follows:

Cup = Full bust - High bust

Full bust is the measurement across the fullest part of your bust. As for the high bust, it is the measurement above the bust. In order to take correct measurements, you need to look at yourself in the mirror and check if the tape measure is straight. Another alternative is to ask someone to please do it.

Once the calculation is done, you can find the measurements below which will give you your cup for a sewing pattern.

Cup A : 2.5cm

Cup B : 5cm

Cup C : 7.5cm

Cup D : 10cm

Cup E : 12.5cm

Cup F : 15cm

Opian patterns are designed for a C cup in mind. If you have a different cup, you will need to adapt it to your size. You can find the method to do a full bust adjustment (FBA) and a small bust adjustment (SBA) in the Pattern making section.
