This specialized calculator is designed to help you find a comfortable and supportive bra during pregnancy and breastfeeding. It guides you through taking measurements that account for the unique changes your body goes through, such as an expanding rib cage and fluctuating cup size. You can use it at different stages to ensure you always have a bra that fits your changing shape.

Standard bra sizing doesn't always work during pregnancy and nursing. Your body is changing, and your lingerie needs to change with it. A well-fitting maternity or nursing bra provides essential comfort and support, can help alleviate back pain, and makes nursing more convenient. Investing in proper-fitting bras during this time is an investment in your own well-being.

Your result will be a recommended maternity or nursing bra size. This size may be different from your pre-pregnancy size. Look for key features based on this result, like flexible wires (or wire-free options), soft, stretchy fabrics, multiple hook-and-eye closures to accommodate a changing band size, and easy-to-use nursing clips. Your comfort is the top priority.

• When buying a nursing bra before your baby arrives, try to ensure the cup has a little room to grow, as your milk coming in will increase your bust size.
• Look for nursing bras made from natural, breathable fabrics like cotton to keep you comfortable.
• Sleep bras for nursing can be a lifesaver for nighttime comfort and to hold nursing pads in place.
• Practice opening and closing the nursing clips with one hand before the baby comes. It's a skill you'll be grateful for!
• Check the fit of your nursing bra every few weeks, as your body will continue to change after you give birth.
