All Macom bras have expandable cups, so you only need to know your current high street bra size, i.e. X-Small (28 - 30), Small (32), Medium (34), Large (36), X-Large (38), XX-Large (40).

The cup will mould to your new cup size.

Please measure the widest part of your waist
if you are inbetween sizes we would recommend going for the larger size

Please measure the widest part of your waist which is usually 2 inches below your belly button and the widest part of your hips which is usually 7 inches below your belly button.

If you are inbetween sizes we recommend going for the larger size.
