STEP 1: Identifying the correct band size
- Place the tape measure just below where your bra sits.
- Hold the tape flat around you making sure the tape is straight across the back and level under the bust.
- Note your measurements in inches and use the chart below to figure out your band size.
- Example: if you measure between 31“ and 32“, your band size is 36.
| 25 - 26" |
27 - 28" |
29 - 30" |
31 - 32" |
33 - 34" |
35 - 36" |
37 - 38" |
39 - 40" |
41 - 42" |

STEP 2: Identifying the correct cup size
- Place the tape measure around the fullest part of your bust, do not pull too tight.
- Make sure the tape is straight across the back.
- Note your measurements in inches and use the chart below to figure out your cup size.
- Example: if your band size is 36 and your cup measurement is 38", start at the band size of 36 and go down the column until you reach 38“ and note the cup size on that row. For our example the bra size would be 36C.

STEP 3: Identifying your sister sizes
TIP: The measurement chart gives you a first idea of what size should be the correct one - but it's not set in stone. Your individual best-fitting size may vary by style and the type of the bra. If you find that you are using the loosest or tightest hook, you might prefer a sister size.
- Sister sizes are bra sizes very similar to your starting bra size identified by the guide. They provide the same overall cup volume while giving you more options for the band size.
- If the identified cup size fits but the band size seems too tight or you wear you bra at the loosest hook, jump one band size up and one cup size down.
- If the identified cup size fits but the band seems too loose or you wear your bra at the tightest possible hook, jump one band size down and one cup size up.
- Use the chart below for identifying your sister sizes. From your starting size move one position to the left or right to find your sister sizes.
- Example: Your individual bra size is a 36C and your sister sizes are 34D for a tighter band size and 38B for a wider band size.
