Our Lingerie - find your perfect fit
Our lingerie runs true to size, so we always recommend taking your normal size. If you aren't sure which size is best, follow our size guide to find the perfect fit for you.
How to measure
You will need a standard measuring tape to take measurements in inches. We recommend taking your measurements without a bra on or wearing an unpadded bra.
To find your band size, measure around your rib cage underneath your bust.
To find your cup size, measure around your over-bust at the fullest point.
To find your cup size, measure around your over-bust at the fullest point.

Find your band size depending on where your under-bust measurement sits between the brackets below. Then find your cup size within that band using your over-bust measurement.
