Benefits of different maternity bras

Wearing a bra that is too small for you can be an uncomfortable experience. It is difficult to know how much your breasts will change throughout the entire maternity and nursing experience, as each woman’s body is unique and will change differently: some mums only gain one cup size, while others increase by three or more cup sizes. For this reason, it is beneficial to wear well-designed bras and tank tops that will adapt to your body’s changing shape and provide a comfortable experience.

During the day a comfortable wire-free, seam-free and supportive nursing bra is the best option. You can start wearing this type of bra during pregnancy when you outgrow your regular bras. When you begin nursing, bras with full drop cups will allow you to breastfeed your baby easily and discreetly.

For easy feedings at night, you should choose a sleep bra that is comfortable, breathable and keeps breast pads in place.

What size nursing bra should I buy?

The first step to find the right bra for you is to get accurately measured, which can be done easily in the comfort of your home or by a professional at a shop. Every woman is unique, and this calculation is the first and most important step.

After being measured, it is best to try on the bra to ensure a proper fit. This will also allow you to test the different bra features like hooks, full drop cups, clips, material, shape, support, discretion, etc.

While trying the bra, unhook the strap clips using only one hand to ensure ease of use. This is an important feature because you will need to open and close them regularly with one hand only while holding your baby.

Step 1:

Measure around the fullest part of the bustline, keeping the tape measure level.
