These charts can assist you in manually determining your bra and cup size.

Step 1: Your Size

Take the tape measure and place it around your body directly below the bust.

Ensure that the tape is firm and is not over the bra or underwire.

Underband (cm)	Australian Size	English Size
63–67	8	30
68–72	10	32
73–77	12	34
78–82	14	36
83–87	16	38
88–92	18	40
93–97	20	42
98–102	22	44
103–107	24	46

Step 2: Your Cup Size

Place the tape measure around your back firmly and then over the fullest part of the bust.

Your cup size can be calculated by the difference between this measurement and the bra size measurement.
