Diana Bralette Sizing
I recommend choosing a size that is 20% smaller than your full bust circumference (multiply by .8). The bralette is meant to be snug around the full bust and the under bust. If between sizes, size down.
Cup size is customized to your body with short rows. A calculator generates instructions for you based on your bust cup depth measurement. Depending on size and the desired bust cup depth, this shaping may be split into 2 sections, with preliminary short rows followed by the cup shaping short rows. See photo for illustration.
Pattern comes in 10 sizes, which are intended to fit a 30”, 34”, 38”, (42”, 46”, 50”) {54”, 58”, 62”, 66”} / 75 cm, 85 cm, 95 cm, (105 cm, 115 cm, 125 cm) {135 cm, 145 cm, 155 cm, 165 cm} full bust measurement.
