What Size should I Buy?
The sizes for our maternity wear are usually the same as non-maternity clothing - so if you were a size 10 before you got pregnant, look for maternity clothes labelled size 10. If you are fortunate enough to be having a multiple birth, we recommend that you go up a size as you will need the room!
Determine your maternity/nursing top or dress size based on your current bust measurement. Measure around the fullest circumference of your bust and refer to the charts below to get the most accurate fit.
For maternity bottoms, measure the largest circumference of your hips by wrapping the tape measure around your hips, just below your growing belly and then refer to the charts below for the corresponding size.
