So comfy, so soft and high wasted for c scar

So comfy, so soft and high wasted enough to sit comfortably above my c section scar. So glad I treated myself to some new undies. Going to by more right now!

Thank you for your lovely review Jessica, so pleased to hear that you love them! x

My fave

This is by far my favourite postpartum item. The fabric is soft but structured, it gives me all the support I need in my lower belly.

Super comfy!

I was worried about the sizing (10/12 or 14/16) however I sized up and they are super perfect, not tight at all and not baggy with still room to give for the growing months! They are super soft and super comfy :)

Very comfy and stretchy, although they do have a tendency to roll down at the top, perhaps the top band could be a little wider but I do like that there's no elastic in the waist to cut in to the mum tum

Seamless stretch moves with your changing body — between sizes? Size up

Yes definitely!  They are made for all women at every stage of life.

Yes — the seamless stretch adapts as your bump grows. The mid-rise fit sits comfortably under a growing belly without rolling or digging in.
