It has been brought to our attention that it isn’t easy to find our sizing information so I have pulled this together to help with any questions.
Small = AU/UK 8-10, US 4-6, Euro 36-38
Medium = AU/UK 12-14, US 8-10, Euro 40-42
Large = AU/UK 16-18, US 12-14, Euro 44-46
X Large = AU/UK 20-22, US 16-18, Euro 48-50
Please note that the design is very generous and forgiving due to the gathering and cut around the neck and under the arms. Depending on which side of the rage you are you can often wear a smaller size comfortably. To give an idea how generous it is around the belly I wore the exact same nightie through all three pregnancies and still had some room (not much mind you) at the end of the pregnancies. Totally fine around arms and neck just finally reached the last few cm/inches of room by 38 weeks and I carry big.
With the dresses the points that tend to require a move up are the neck and chest areas as these zones have little to no give. The arm elastic can be replaced, hem let down (we give you a generous amount to grow with) and the tie can take in the excess around the bodice.
