That is why a nursing bra should be soft and wire-free
A soft nursing bra is designed for a breast that is constantly changing. During nursing, the size of the breast fluctuates between empty and full, often several times a day, and a bra that adapts to the body rather than constricting it makes all the difference. That is why the bras you find here are seamless and wire-free: there are no hard edges that can press on the milk ducts, and no seams that chafe against a tender breast.
Avoiding underwires is not just about comfort. Hard pressure on a full breast can in some cases block the milk ducts and cause tender lumps or, in the worst case, mastitis. A soft, stretchy cup provides room, whether the breast has just been emptied or is filling up again. If you are unsure whether you need an underwire at all, you can read more in our overview of wire-free nursing bras.
Carriwell made some of the world's first seamless nursing bras almost three decades ago, and seamless design is still at the core: a bra that almost disappears against the skin and moves with you instead of against you.
How to find the right size
Size is what most people are most unsure about, and for good reason: your breast is not the same from week to week when you are nursing. A nursing bra must therefore fit when the breast is empty and provide room when it is full. That is one of the reasons why the soft, seamless models are so practical. They stretch across several sizes instead of locking you into one cup.
You measure by taking two measurements: the circumference just under the breast gives you the band size, and the circumference over the fullest part of the breast gives you the cup. The difference between the two numbers determines the cup size. It is best to measure at a time when the breast is not completely full, so you get a realistic average. If you are still pregnant when you buy, remember that the breast typically grows further when the milk comes in during the first few days after birth.
If you need to approach it methodically, we have put together a step-by-step guide in our bra size guide, and broader help with choosing a style in our bra guide.
One-handed opening that works with baby in your arms
When you are nursing, you rarely have two free hands. That is why the opening on a nursing bra is just as important as the cup. The styles here have drop cups that can be unhooked with one hand, so you get full access to the breast without having to put the baby down or fumble with closures on the back. The click is located up by the strap, where you can easily reach it while baby lies ready.
It may sound like a small thing, but it is what you will notice most in practice when you are nursing ten or more times a day. An opening that gives way immediately means fewer tears from a hungry baby and less hassle for you in the middle of the night.
Soft nursing bra for nighttime
At night you need something completely different than during the day. You need to be able to sleep on your side, nurse lying down, and avoid having a hard band press against you while you lie down. A sleep bra for pregnancy and nursing is made precisely for this: extra soft, without hard details, and easy to open when baby wants to nurse in the dark.
Many also use a soft sleep bra to keep nursing pads in place at night, so milk that leaks does not end up on the bedsheets. It makes nighttime nursing calmer, both for you and for the sheets. If you are lying down and nursing several times, you will notice how much a pressure-free bra matters for whether you can even settle back down afterward.
Silk, organic cotton, or extra support
The soft nursing bras come in several varieties, depending on what is most important to you. If you want the softest feel against the skin, the silk-soft nursing bra is a good choice: light, smooth, and almost unnoticeable under clothing. If you prefer a natural material close to the skin during a time when the breast is sensitive, then look at the organic maternity and nursing bra.
If you have a larger or heavier breast that becomes even heavier with milk, soft must not come at the expense of support. Here, a wide, elastic band under the breast is the key: it carries the weight and relieves pressure on the shoulders and back, without the need for an underwire. The original model with a wide underband is available individually and in a practical 2x Seamless Original Maternity Nursing Bra.
How many nursing bras do you need?
A realistic minimum is two to three. One on your body, one in the wash, and preferably one extra, so you are not left without one the day milk or your baby's accident sends two into the hamper at once. Many find it practical to have a soft daytime style and a separate sleep bra, because the needs are so different.
That is exactly why a 2-pack makes perfect sense for most: you always have a clean one ready. If you would rather put together your own selection across different styles, you can see the entire range under maternity and nursing bras.
Buy already during pregnancy
You do not need to wait until after birth. The breast begins to change early in pregnancy, and many become tender long before their due date. A soft, seamless nursing bra also works as a maternity bra because it stretches with the body instead of having to be replaced every time you go up a size.
A good time to get one is toward the end of pregnancy, when the breast is close to the size it will be around birth. Then you will have it ready in your bag for the first few days after birth when the milk comes in. Dear, buy it well in advance and lay it out with the rest of your maternity clothes, so you do not have to think about it when you have plenty else on your mind. You are not alone in being unsure, and it is perfectly fine to try a few things out until something feels right.
