Size & Fabric Guide
Crafted from our signature mocoform fabric, designed to move with you through every stage of motherhood.
Silky-soft, breathable and sculpting in all the right places, it offers supportive stretch that adapts to your body from pregnancy to postpartum and beyond.
Fit notes
If you’re between sizes, consider:
- SIZING down for a more supported, compressive feel
- SIZING up for a softer, more relaxed fit
For breastfeeding mums (sports bras)
Our nursing sports bras are designed to:
- Allow you to easily breastfeed while wearing your sports bra
- Allow easy one-hand clip access
- Provide support without feeling restrictive
- Stretch with cup size fluctuations
If your cup size has increased significantly, we suggest sizing up for comfort.
