Size Guide
Which size is right for me?
Simply choose the size you normally wore before pregnancy.
XS/S → usually sizes 34–38
M/L → usually sizes 40–44
Size 38 before pregnancy?
We recommend XS/S.
The adaptive waistband adjusts to your changing body and grows with you throughout pregnancy – without feeling restrictive.
Between two sizes?
Choose the smaller size for a more fitted look, or the larger size if you prefer a more relaxed fit.
