23 Mai Paris
BREASTFEEDING CLOTHES
All of our nursing clothes are designed with discreet side openings—zippers that are invisible from the outside, allowing you to access your breast in seconds without having to lift your shirt or take it off. The opening closes perfectly, so no one notices a thing.
We recommend choosing your pre-pregnancy size. Our clothes are cut with enough room to accommodate postpartum body changes. If you’re unsure between two sizes, choose the larger one—especially if you’re breastfeeding, as your bust is often larger during this time. Our size guide is available on every product page.
Yes. The side openings allow you to use a breast pump without having to take off your clothes. This is especially convenient for discreet pumping sessions at the office or on the go.
Most of our pieces can be worn starting during pregnancy, especially T-shirts and sweatshirts. The fit is loose enough to accommodate a growing belly. For the final months, we recommend sizing up.
Our embroidery is handcrafted in our Parisian workshop and is designed to last. We recommend machine washing at 30°C, inside out, without a spin cycle. Avoid using a dryer to preserve the threads and colors for as long as possible.
Our garments are made from 100% cotton—soft, breathable, and ideal for frequent contact with your baby’s skin during feedings. No irritating ingredients, no chemical treatments.
Some of our items can be personalized with your baby's first name or a word of your choice. Personalization options are listed directly on the relevant product page.
Embroidered items are made to order in our workshop. Please allow about 7 business days for shipping, and up to 15 days during peak periods. Once your order has been shipped, you will receive an email with your tracking number.
Can I return an item if the size doesn't fit?
Items that are not embroidered or printed can be returned within 14 calendar days of receipt, provided they are unwashed and still have their original tags attached. Embroidered items are final—no returns or exchanges, as they are custom-made for you. If you have any doubts about the size, please feel free to contact us before ordering at bonjour@23maiparis.com.
Is shipping free?
Shipping is free in mainland France for orders of €120 or more. For orders below this amount, shipping costs vary depending on the delivery method selected. We also ship throughout Europe and internationally.
Are these clothes suitable for breastfeeding in public?
Absolutely. That’s exactly why they were designed. The openings are invisible when closed, and you can access your breast discreetly, without drawing attention. You can breastfeed anywhere—at a restaurant, on public transportation, at a friend’s house—without having to cover up if you don’t want to.
How long can I wear these clothes after breastfeeding?
Indefinitely. These are, above all, beautiful garments that can be worn well beyond the breastfeeding period. The side opening is discreet, and the embroidery is timeless. Many of our customers continue to wear their 23 Mai Paris pieces 23 Mai Paris after weaning.
Non-embroidered items may be returned within 14 calendar days of receipt, provided they have not been washed and still have their original tags attached.
