Measurements explained

  • Underband

    Underband sizes are in even inches... 28, 30, 32, 34 etc.

    If you measure an even number, that is your underband size (up to 0.5 over, so 32.5 is still a 32 underband).

    If you measure an odd number you will be the next even number e.g. 31 or 31.5 becomes a 32.

  • Cups

    A cup size is the difference in inches between your bust measurement and your first underband measurement. e.g. 30 inch underband / 36inch cups = +6

    This is a 30E bra size. See our See our grid to the right which shows this visually.

  • ... it's basic maths

    Here to demystify bra sizing, it is as simple as this. If you're still not sure, just book in for a fitting here.

Sister sizing

There are two simple principles to 'sister sizing':

1. If you go up a back size, go down a cup size. e.g. a 30E > 32DD

2. If you go down a back size, go up a cup size. e.g. a 36DD > 34E

Go up a back size, stay the same cup size = extra room in the cup

Go down a back size, stay the same cup size = tighter cup

Checking the fit

Make sure your underband is fastened on the loosest setting & straps are firmly fastened in a 'X' shape

  • Cups

    ✔️ Breasts comfortably inside

    ✖️ Breasts spilling out at side or lots of cleavage (cup size too small)

    ✖️ Gaping fabric (cup size too big)

  • Underband

    ✔️ Fits firm + level on loosest hook

    ✖️ Rides up your back or can pull out more than 1 inch (too big)

    ✖️ pinching or cannot fasten (too small) … this could be your cup size. If you can do it up at the front & it fits, your cup size is too small.

  • Straps

    ✔️ Can only lift up to 1 inch away from your shoulder
