While you can wear the pregnancy leggings (Saviour Maternity Legging) postpartum, you won't receive the specific recovery benefits for your abdominal muscles that are featured in the postpartum leggings (Restorer Postpartum Support Legging). Conversely, we do not recommend wearing the postpartum leggings during pregnancy as there is no room for your belly to grow and they feature moderate targeted compression panels to help support your abdominal recovery that could potentially be detrimental to your growing baby.We recommend purchasing both pairs to experience the full range of benefits throughout your pregnancy and postpartum journey. Each pair is designed to provide optimal comfort, support, and recovery at the appropriate stage. They share many fabric technologies and style similarities, below are the differences.Key differences between the two - Pregnancy Leggings:Designed to support your body throughout your entire pregnancy.Features graduated compression to improve blood flow and circulation, which is essential for your baby's development (maternal blood flow to placenta feeds and nourishes your baby).Flexible belly panel grows with your belly from the first to the third trimester (even with multiples!).Postpartum Leggings:Specifically designed to aid in postpartum recovery, particularly for diastasis recti and C-section healing.Features targeted compression through the belly to support your abdominal muscles as they realign.Provides comfort and support for C-section recovery, including avoiding seams near the incision.
