All Love Notions patterns closely follow the ASTM Standards for Body Measurements. Ladies patterns are drafted for the average 5’5″ height and B sewing cup. Did you know that sewing cup sizing and bra cup sizing are totally different? Pattern cup size is based on the difference between your high bust and full bust. To get a better fit, especially in knits, go by your high bust measurement. This way the neckline and shoulders are more likely to fit better and not need adjustment.
