How to choose the right nursing bra size?

Los Nursing and maternity braspaly aey role in the first months of your baby's life, when your body is recovering after birth and you should feel especially comfortable and secure.
When buying nursing bras, it's not just the fabrics they're made of that matter (breathable, flexible, and comfortable is best): it's also essential to choose a cup that guarantees perfect coverage for your breasts, strategically distributes pressure in the area, and provides the support you need.
At Leonisa, we understand the needs of women at every stage of their lives, and we are aware that these needs are very specific during breastfeeding.
That's why we've developed this article explaining what aspects you should consider and how to choose the size of your nursing bra.
What is a nursing bra?
Nursing bras are underwear designed to provide comfort and facilitate feeding your baby.
Unlike traditional bras, their cups open easily to reveal the nipple, making them especially useful for breastfeeding anytime, anywhere.
Some of them even have space to place nursing pads to prevent stains or deformities in the breasts that could affect the appearance when dressing.
Nursing bras are typically made of soft, stretchy materials to accommodate breast size changes during pregnancy and breastfeeding, and provide the necessary support to prevent discomfort and common problems, such as mastitis.
When should you start wearing a nursing bra?
Many women wonder when to start using a nursing bra.
We recommend purchasing your nursing bra one or two months before your due date, as by this time your breasts will be a similar size to what they were during the first few months of breastfeeding, and it will likely be easier to get the right size.
Additionally, you can start wearing this garment in this final stretch of pregnancy to get used to it and check that you feel comfortable.
On the other hand, experiencing breast tenderness from the early stages of pregnancy is quite common, and if conventional bras are uncomfortable or bothersome, you can wear a nursing bra, which is gentler on the skin, throughout your pregnancy.
In the end, the most important thing is your comfort and how you adapt to the changes in your body.
How to choose a nursing bra size (and other interesting tips)
7 aspects to take into account
- Material.Maternity and postpartum underwear should be made of soft, flexible, and breathable fabrics.
- Adjustable straps. Nursing bras have wider straps to provide adequate support. Adjustable straps are recommended so you can adjust them to your changing body.
- Reinforcements in key areas. If you have large breasts, look for a nursing bra with targeted reinforcements at the base and sides. This extra support will be very comfortable and help maintain the shape of your breasts.
- Front clasp opening. The easy-to-open front of the bra allows you to breastfeed your baby comfortably and discreetly without having to remove your garment.
- Maximum fit. Having multiple levels of adjustment in the back is essential. This way, you can wear the bra from pregnancy until you're done breastfeeding.
- Smooth, seamless design. A discreet color and seamless design will conceal the bra, so it won't show under clothing. You can wear it every day from the very beginning of your pregnancy.
- Ease of washing. Finally, make sure the nursing bra you choose is easy to wash and maintain, as even if you have several styles, you'll need to wash them frequently.
Tips for choosing the right size for your nursing bra

Choosing the correct nursing bra size is very important.
We know that every woman is unique, and that sizes can vary between manufacturers, but these tips can serve as a general guide.
Our goal? To help you find a bra that fits your body well and offers support without compressing or leaving gaps.
- Measure your underbust band. You can place a tape measure just below your breasts, making sure it's level and snug, but not tight.
- Measure your chest circumference. That is, at the fullest part of your breasts. Keep the tape level and don't press too hard.
- Calculate the difference. Subtract the underbust measurement from the overbust measurement. The difference will help you determine your (approximate) bra cup size.
Finally, remember that specialized manufacturers, like LEONISA, have a size guide so you know which size best matches your measurements.
You can calculate it in centimeters or inches, and you have its equivalent with the approved sizes (S, M, L, XL, etc.).
How should a nursing bra fit?
A nursing bra should fit snugly, but not cause excessive pressure or be loose.
If it's too tight, it can compress the milk ducts and increase the risk of blockages and mastitis; if it's too loose, it can cause discomfort during daily activities and contribute to loss of breast firmness.
Another common question many women have is whether to choose underwired or non-underwired nursing bras.
Underwire bras offer additional support and can help maintain the shape of the breasts, although it is important that the underwire does not press against the breast tissue.
Non-wired bras are more flexible and comfortable, especially for sleeping and during the first weeks of breastfeeding, or when breasts are more sensitive.
