How to choose your lingerie

Which model should I choose?
During pregnancy and nursing, you will experience an increase of one to two cup sizes and as well as an increase of your band size. The most important factor therefore is good support. As a consequence, we recommend a style which is underwired. The underwiring should be of the right size and flexible enough to follow the movements of your body. The materials should be soft and comfortable, with a maximum percentage of elastane to ensure the bra remains fitted throughout the day, in spight of the changing volume of your chest due to the gradual production of milk. Styles that are lined will retain their shape better and will provide you with more support. Microfiber is preferable to cotton as it dries faster.

How many nursing bras should I have?
This depends on the amount of time you intend to breastfeed for. A minimum of 2 bras will allow you to always have one to replace the other when it needs washing. Also consider an extra for nighttime. After three months however, as your chest decreases in size, you might need to consider purchasing new bras in a smaller size.

How do I choose my size?
Depending on your increase in size during your pregnancy, this will help you choose your size for nursing bras. Our brands’ experts have advised that it is best to opt for the bra size you reach in the sixth month of your pregnancyfor the size of your nursing bra. For the first three weeks after giving birth, the chest will be particularly enlarged and a nursing camisole will be more comfortable. You can also purchase a bra strap extender that will enable the bra to adapt to these changes in size.

Start by measuring your band size:
The band size is the ribcage measurement directly UNDER your bust. Use a tape measure to determine your size. Take care not to measure any part of your breast when taking this measurement. Make sure the measuring tape stays level at the back (use a mirror or enlist the help of a friend). Take a note of this measurement and find the corresponding bra size in the first table below.

Cup size:
Measure yourself at the most voluminous part of your bust, preferably while wearing a comfortable and non-padded bra. Hold the measuring tape very straight but without tightening it, making sure it stays a little loose. Take a note of the result and calculate the difference between your band measurement and your cup measurement. This will give you the corresponding cup size: B, C, D etc.
