Maternity Size Guide

Judging your size during pregnancy isn't always easy, but our collection is designed to grow with your changing curves, providing a flexible fit before, during and after pregnancy. For the best possible fit, simply select your pre-pregnancy size.

So for example, if you usually take a size 6, stick with a Seraphine size 6 throughout - Simple!

For bra sizes, please see our separate maternity & nursing bra advice page.
