Intimates

Comfort is key. Our line of intimates perfectly adapts to your changing needs both during and post-partum. Our maternity bras with nursing function provide comfort and support as you transition from pregnancy to nursing.

band size

Wrap the measuring tape under your bust at the bottom of your bra around your rib cage. Be careful to keep the tape level from front to back. Round up to the nearest half inch.

cup size

Wearing a non-padded bra, wrap the tape around your bust over your bra at the fullest point. Keep the tape level around the back and fairly tight around the body. Use the chart to determine your cup size.

 

Sizing Tips

You should buy your maternity bra at start of your second trimester.
The bra should fit on the tightest hook when you buy it, so that you can loosen it as your body grows. Please visit our store for a personal fitting.
