Cup sizes for Banksia
Sewing-cup sizes are different to bra-cup sizes and are calculated using the difference between the over-bust and full-bust measurements. This means that most folks will not need to do a FBA to increase the size of the bralette.
Leila's Banksia Bralette
Leila wears a 40H US Bra size RTW, but her sewing-cup size is D, not H.
Leila's measurements Upper-Bust 46" (117cm), Full-Bust 50" (127cm), Under-bust/Band 40" (101.5cm)
In the Banksia Bralette, Leila makes Size F, with the D Cup pieces.
The bralette pictured above has wider shoulders than the final version of the pattern.
Choosing your size
Choose your size for the Banksia based mostly on your under-bust measurement, as each of the cup-sizes will accommodate a wide-range of breast shapes and sizes.The D cup piece is intended for a 4" difference between over-bust and full-bust, and the B cup is intended for a 2" difference.
Narrow Shoulders? If you have narrow shoulders, this could throw off the sewing cup-size measurements. Most folks know when they have narrow shoulders (I definitely do), so we encourage you to use the narrow-shoulder pieces if you know that's you.
