What are the must-have items for a winter nursing wardrobe?

Putting together a winter nursing wardrobe doesn't mean you have to start from scratch—just a few key pieces are enough to cover every situation during the cold season, from nighttime feedings to going outside in the freezing cold.

The long-sleeved, thick-cotton Breastfeeding t-shirt is the foundation piece: worn as a base layer at all times, it maintains core warmth and ensures that your belly stays covered no matter what happens during feedings. The winter nursing sweater with discreet side zippers is the essential second layer—warm, stylish, and functional. Thenursing sweatshirt offers the same functionality with a more casual vibe, perfect for everyday wear at home. The nursing sweater dress is this season’s all-in-one piece: ultra-snug, its built-in zipper openings make nursing a breeze. And the nursing pajamas round out the winter wardrobe for more restful nights. With these five pieces, you’re covered for every winter situation—from the first feeding in the morning to the last one at night.

What fabrics should you choose for winter nursing clothes?

Choosing the right fabrics is one of the most important considerations when putting together a winter nursing wardrobe. There are two factors to balance: staying warm without overheating, and ensuring the fabrics are gentle on postpartum skin, which is often more sensitive.

Thick cotton is the go-to fabric for winter base layers: natural, breathable, and soft against the skin, it provides insulation without trapping moisture and remains comfortable both indoors and outdoors. Cotton blended with modal offers an even softer and slightly more thermoregulatory option, ideal for moms who tend to get warm easily while breastfeeding. The stretchy “knit ” fabric used in knit ’s nursing sweater dresses and sweaters provides extra insulation and a cozy, enveloping softness that’s especially appreciated in winter. Avoid as a base layer: non-breathable synthetic fabrics that trap heat and sweat evenly, making them uncomfortable during feedings and when there are temperature fluctuations between indoors and outdoors.

How does the closure system on 23 Mai Paris nursing clothes work in winter?

All 23 Mai Paris nursing clothes—T-shirts, sweaters, sweatshirts, dresses, and pajamas—feature the same opening system: two discreet side zippers, one on each side of the chest, which are invisible when zipped up. In winter, this system is especially useful because it allows access to the breast without having to lift or remove the garment; the stomach and back remain fully covered and warm throughout the entire feeding session.

Simply unzip the desired side—left or right—to access the chest in just a few seconds. The rest of the body remains fully covered. When layering a Breastfeeding t-shirt + nursing sweater, both zippers open at the same time on either the left or right side, allowing for access that’s just as seamless as with a one-piece garment.

What is layering, and how can you use it for breastfeeding in the winter?

Layering is the most effective way to breastfeed comfortably in the winter. The idea is to wear several separate layers that you can unbutton or remove individually, rather than a single, very warm garment that you have to take off completely to breastfeed.

The three-layer “ 23 Mai Paris ” method. First layer: a long-sleeved “ Breastfeeding t-shirt ” made of thick, fine, stretchy cotton with a side zipper. It will never shift: it maintains core warmth and covers the belly during all feedings. Second layer: a nursing sweater or sweatshirt with a side zipper—this is the layer that opens for feeding. Third layer: a coat or jacket that opens easily for outings. To breastfeed, simply open the side zipper of the second layer. The belly is covered by the first layer, and the back is protected by the third. Breastfeeding takes place without ever exposing the baby to the cold.

How do you choose the right size for winter nursing clothes?

The golden rule for all nursing clothes 23 Mai Paris, whether it’s winter or summer: stick to your usual pre-pregnancy size. Stretchy fabrics are specifically designed to adapt to postpartum curves without requiring you to go up a size.

In winter, if you plan to layer your clothes—such as a Breastfeeding t-shirt under a nursing sweater—make sure the second layer is slightly roomier to accommodate the first. If you’re unsure between two sizes for any winter garment, always go with the larger one: a slightly roomier garment leaves more room for layering, is more comfortable, and provides valuable freedom of movement during feedings. Each product page includes a detailed size guide.

Can you wear your winter nursing clothes during pregnancy?

Yes, and that's one of the great advantages of the items at 23 Mai Paris. Most sweaters, sweatshirts, sweater dresses, and long-sleeve T-shirts can be worn as early as the 4th or 5th month of pregnancy—their stretchy fabrics naturally conform to your growing belly without constricting or riding up.

It’s a particularly worthwhile investment: a mom who buys her winter nursing sweater in her fifth month of pregnancy can wear it for 4 months during pregnancy, 12 months or more while breastfeeding, and for several more winters after weaning, thanks to the openings that are invisible when closed. One garment, several years of use.

Which 23 Mai Paris tires should you choose based on your winter driving conditions?

Every mom has a different winter style—some are sensitive to the cold, some get warm easily, some are often out and about, and some prefer to stay home—and the best pieces to choose vary accordingly.

If you feel the cold easily: go for the nursing sweater knit and the nursing sweater dress—their cozy fabrics provide the best thermal insulation. Pair them with a long-sleeve T-shirt as a base layer. If you tend to get hot easily while nursing: opt for the nursing sweatshirt as a base layer instead of the sweater knit —it’s more breathable and easy to take off between feedings. If you’re often out and about, the three-layer system is perfect for you: long-sleeve T-shirt + nursing sweater + coat. If you mostly nurse at home, the nursing sweater dress on its own, worn with warm tights, covers all your needs. If you’re returning to work in the winter: opt for nursing T-shirts and tops with a discreet zipper under a blazer—they’re invisible during meetings and practical for pumping at the office.

Is a nursing sweater dress really worth the investment in winter?

Yes, and it’s often the item moms wish they’d bought sooner. The nursing sweater dress is the all-in-one solution for winter: a single piece to slip on in the morning, a complete look, built-in zipper openings that make breastfeeding a breeze, and a cozy, knit fabric that keeps you warm from the first feeding of the morning to the last of the evening.

Paired with warm tights and ankle boots, it makes for an elegant outfit for going out. Worn on its own with thick socks, it’s the ultimate cozy piece for days at home with the baby. And its zippers—which are completely invisible when closed—make it a piece you’ll continue to wear long after weaning.

What is the difference between a winter nursing sweater and a " knit " nursing sweater?

Both are designed for winter, but with slightly different approaches.

The winter nursing sweater is the versatile piece for the cold season: warm, stretchy fabric, discreet zipper openings, and a cut that adapts to any situation—whether it’s everyday life, going out, or the office. It pairs effortlessly with any outfit and looks just as good with jeans as it does with a dress. The“ knit ” nursing sweater takes elegance and warmth to the next level: crafted from a thicker, more structured “ knit ” knit, it offers superior thermal insulation and a more polished look. It’s the perfect choice for special occasions, family dinners, or very cold days. Its knit knit is best worn over a long-sleeved Breastfeeding t-shirt to prevent direct contact between the wool and sensitive skin.

How can you care for your winter nursing clothes to make them last longer?

Proper maintenance significantly extends the lifespan of winter tires and preserves their thermal properties and elasticity.

For all items: Wash inside out at a maximum of 30°C on the delicate cycle—the universal rule that preserves fabrics, colors, and zippers. Tumble drying and bleach are strictly prohibited for all items; the heat from the dryer compresses the fibers and reduces elasticity, which is particularly harmful to winter fabrics. For “ knit ” sweatersspecifically: it is essential to dry them flat to preserve their shape—never on a hanger, as this distorts the knit. Wait until after the first wash before using an iron or steamer. Forembroidery: always iron inside out, never directly on the embroidery. Each product page details the specific recommendations for each item.
