A BEGINNER’S GUIDE: SEWING PATTERNS FOR DIFFERENT BUST CUPS

What bust cup size am i?

What cup size am i?

Most patterns are drafted to be suitable for a B or C cup. Check out our Choosing a sewing pattern fro your body shape blog post, which has a list of cup sizes that different designers draft for. You can also download free size chart templates to record your measurements. In sewing patterns, cup size is the difference between your full bust and upper/high bust measurement (note: this is not the same as bra size).

Bust – this is the measurement around your body across the fullest part of your bust, often your nipples. Make sure you keep the measuring tape straight as you record the number so that it doesn’t dip at the back. Check this in a full length mirror.

Upper bust – this is the measurement around your body that is taken above your bust. Keep the measuring tape straight and measure just under your armpits. If you have a larger or smaller bust than the typical B/C cup, this will be useful to know for doing full or small bust adjustments to bodices.

To calculate your pattern cup size, follow the method above to measure your upper bust. Next subtract your upper/high bust from your full bust measurement and use the list below to work out your pattern cup size.

Pattern cup size = full bust – upper/high bust

1″ = A cup

2″ = B cup

3″ = C cup

4″ = D cup

5″ = DD cup

6″ = DDD cup

For example, my bust size is 38” and my upper bust is 34” so I would be a D cup. This makes sense with my experience of having to typically add 1-2” to the bust of patterns as part of a FBA, which are usually drafted for a B/C cup.
