Our Sono Vaso maternity fit is designed to correspond directly to your normal (pre-pregnancy) clothing size. To use our sizing guide, please refer to your pre-pregnancy size below and choose the corresponding Sono Vaso maternity size. You can also check your current pregnancy bust and hip measurements to confirm your size.

To help you select the right size for you it's best to follow the general rule that your pre-pregnancy size will correspond to the maternity size below based on the standard pregnancy weight gain of 12-14 kilos (25-30 pounds). However if your weight gain is higher or if you are carrying twins or multiples (congratulations!) - then please choose one size up from your normal size.
