LOVE these, so comfy!
Was a bit to order with no return option & the sizing but love them! Super comfy, will be ordering more.
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.
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 :)
So soft and comfortable! Not line free but who cares when they are so comfy!
