Generally, Bellyssimo maternity clothing should easily pair up with your pre-pregnancy size, but if you have any further doubts, use the size chart below to find your best fit!

The sizes we offer for our pregnancy range are sizes 32 to 38. 

If your pre-pregnancy size is a size 32, then you should purchase the Bellyssimo size 32.

However, if you would like to be more comfortable, it is advisable that you choose a bigger size.
This also gives extra space for any weight gain, especially if you tend to pick up a lot of extra weight during your pregnancy. Some of our pregnancy styles are specifically made tighter around the bust to create a sexier look.

Our sizing is very standard and we have a high success rate with our fits and rarely have exchanges. 
For pregnancy tops your usual size is recommended and for pregnancy bottoms it is advisable to order one size bigger.

If you are noticeably taller or shorter than the average height, please email us so we can make the necessary adjustments to the lengths of your pregnancy garments.

If you are a size 40 and above, it is imperative you send us your measurements upon ordering:

  • For Pregnancy Tops, please send your bust and shoulder to floor measurement.
  • For Pregnancy Bottoms, please send your hip and shoulder to floor measurement. 
  • For Pregnancy Dresses, please send your bust, hip and shoulder to floor measurements.

If you require a bigger size delivery will be an extra 1-2 days, as we will need time to manufacture. The biggest we can go up to is a size 48 and sizes over 42 will incur a 15% increase on the price of a garment due to the extra fabric used.
