If your bra falls short in any of the above areas, chances are you’re wearing the wrong size. And
that’s not just a pain when it comes to looking your best – it can cause some serious back ache,
rubbing and skin irritations too. To help you achieve the very best comfort and support, we’ve put
together these measuring guidelines – but they’re by no means the be-all and end-all of bra fitting.
Every woman is different, and for that reason, we advise you to use your measurements as a
starting point, trying on a selection of styles and sizes until you find the fit that’s perfect for you.
And with Oola’s free returns policy, it couldn’t be easier: shop to your heart’s content, keep the
bras you love and let the postman take care of the rest.
- First, find your underband measurement. Keeping the tape measure quite tight, measure
around your ribcage just below the bust, and check in the mirror to make sure it's level all
the way around. Make a note of your measurement in inches.
- Now find your cup size. Measure around the fullest part of your bust, again checking in
the mirror to make sure the tape is level.

yourself a six monthly measuring reminder and keep your breasts beautifully supported for life.
