It envelops the newborn in a reassuringly warm, cocoon-like sensation, while respecting the fragility of their skin and movements. Designed to be worn from the moment they leave the maternity ward, it contributes to their first sense of comfort and security.

A baby vest is a small garment that wraps around the infant's torso and arms. Worn over a bodysuit and pajamas, it provides extra warmth while remaining soft against the skin. It opens completely (front or side), which reduces handling during the first few days and reassures the baby with consistent warmth.
- Thermal protection : ideal when thermoregulation is not yet mature.
- Respectful dressing : full opening to avoid passing over the head.
- Versatility : home, maternity, short outings, skin-to-skin contact.
The maternity bra: an essential item in your baby's layette
It's an essential part of your maternity bag, just like bodysuits and pajamas, as we explain in our article dedicated to preparing your maternity bag. It can be worn from the very first hours, over the bodysuit, to create a warm, cozy atmosphere. Wrap-style cardigans are particularly recommended: they open completely at the front and close at the side (with buttons or ties), making it easier to dress a still-fragile newborn. This style is found in many newborn wrap cardigans .
Comfort and safety are essential when choosing a baby vest. Soft seams, careful finishing, and breathable fabrics help prevent chafing and irritation. A well-designed vest stays in place without constricting, moves with the baby's natural movements, and makes daily care easier.
The different models of baby vests
Wrap-style bralette (crossover)
The wrap-style baby cardigan is especially popular for the first few days. Thanks to its crossover opening at the front, it allows you to dress the newborn without having to go over the head, minimizing handling. This style is ideal in the maternity ward, where comfort and simplicity are essential.
A maternity advantage: it opens fully, closes with buttons or ties on the side, and doesn't go over the head. It's the easiest model to handle in the first few days.
Tie-on bra
It's similar to a wrap-style cardigan but with adjustable ties. It adapts well to the baby's shape, just requires a secure knot (not too loose, not too tight).
Button-front or back bra
Elegant and stable. It remains practical in the front; in the back, it offers a very nice fit but requires more care when dressing. Often preferred for first photos and outings.

What material should you choose depending on the season?
The material matters as much as the shape. To respect the delicate skin of newborns, opt for natural fibers.
Merino wool : ultra-soft, thermoregulating, breathable, and naturally hypoallergenic. In winter, it keeps you warm without overheating; in the mid-seasons, it wicks away moisture and remains comfortable. For styles suitable from birth, discover our merino wool cardigans .
Cotton : lightweight and breathable, practical in summer or in heated indoors.
Thick velvet/knits : best suited for cold environments, with temperature monitoring to avoid overheating.
Sizes and quantities: how many bras should I plan for?
Having several bras on hand allows you to alternate them in case of regurgitation or washing.
- Maternity (short stay) : 3 bras minimum.
- Back home : 4–6 bras depending on the season and laundry frequency.
Suggested sizes : Premature (from 40 cm), Newborn/0 m (46–50 cm), 1 m (50–54 cm), 3 m (54–60 cm). Choose according to the gestational age and estimated size.
Putting together a harmonious trousseau
The baby vest pairs perfectly with a hat (for temperature regulation), booties (to keep feet warm), and soft leggings. For a ready-to-give gift, a coordinated baby gift set is always a safe bet.
