How to find Your perfect bra size

Fill in the measurements of your band and bust size into the La Perla Size Calculator to find your perfect fit.

What you'll need before you start:

  • Make sure you are wearing a non-padded bra or lightly line bra.
  • A tape measure.
  • A mirror to check that you're measuring correctly.

Step 1

Measure your band

1 To measure your band size, place the tape measure flat against your skin - directly under your breast.
2 Ensure the tape runs horizontally around your torso and is at the same height under your breast as your back.
3 Allow your arms to hang down naturally and breathe as normal. Allow space for one finger between your skin and tape measure at the end.
4 Round the measurement up to get an exact number in cm or inches. Enter this value into the "band" section of the tool.

Step 2

Measure your bust

1 To measure your bust size, place the tape measure flat against your skin against the largest part of your breasts – this will usually be at the height of your nipples.
2 Once again, ensure the tape is horizontal and at the same height on your front and back.
3 Round the measurement up to get an exact number in cm or inches. Select this value from the 'Bust Size' section of the calculator.
4 Click ‘find my size’ to calculate your perfect La Perla Bra fit.
