Baby girl Christmas dresses and baby boy outfits: how to choose from 0 to 12 months
In the first few months, the most practical festive piece is almost always a romper; dresses and ceremony outfits come in towards the first birthday. Here's what changes with age, for girls and boys, plus the details to check before Christmas lunch.

Christmas dress or romper for a baby girl just a few months old?
The boutique's Christmas range has almost 300 pieces for 0 to 12 months. In the smallest sizes for girls, there are very few actual dresses, and the choice is mainly between rompers. The reason is a practical one.
At a few months old, a baby girl spends Christmas lunch in someone's arms, in the pram or on the changing table. When you hold her, a dress with a skirt tends to ride up; it has to be lifted for nappy changes, and she'll still need socks or tights underneath. A romper is a single piece: it stays put when she's held and looks complete in photos. Velvet, lace, tartan and bows all feature in rompers too, so there's no shortage of festive spirit.
Before you choose, check how the garment opens. The American Academy of Pediatrics (AAP) recommends poppers or zips at the front rather than the back, and points out that fastenings down both legs make nappy changes easier. If you can't tell from the photos, ask us on WhatsApp.
The same logic applies to a Christmas outfit for a baby boy: in the first few months, alongside two-piece outfits, there are all-in-one sleepsuits and rompers. When dressing him, the AAP suggests putting the legs in first and then the sleeves; if a garment goes over the head, stretch the neck opening wide with your fingers and keep it away from his face and ears. The Australian service Pregnancy, Birth and Baby adds: one arm at a time, without pulling.
What changes in Christmas clothes between 0 and 12 months?
The table sums up what you'll find in the Christmas collection by age, for girls and boys, and what's worth checking at each stage.
| Age | For her | For him | What to check |
|---|---|---|---|
| 0–3 months | Mainly rompers. Very few actual dresses. | Outfits, sleepsuits and rompers. | An all-in-one, with fastenings at the front and down the legs for changes (AAP). |
| 3–6 months | Rompers and the first dresses. | Dungarees and outfits. | A dress needs socks or tights. With dungarees, check the product page to see whether the shirt is included. |
| 6–12 months | Mainly dresses. | Outfits, dungarees and ceremony outfits. | Velvet and collars for lunch and photos, plus a simple change of clothes in your bag. |
The table describes what's in our range for each age. For sizing, message us on WhatsApp with your baby's age, height and weight.
Which Christmas dress or outfit to choose, age by age?
From 0 to 3 months: rompers, sleepsuits and outfits
For girls, the choice is almost entirely rompers: velvet with lace, from Isabel and Fofettes, for a smarter lunch; chenille or warm cotton, from Bebè Margò and Sardon, for a celebration at home. For boys there are outfits in warm knit, sleepsuits in chenille or wool blend, and rompers with tartan or smocking.
At this age, fabric matters: your baby wears it for hours, often passed from one pair of arms to another. According to the Italian magazine Nostrofiglio, chenille is well suited to being indoors in winter because it doesn't overheat, and warm cotton – that is, a brushed jersey or interlock – keeps babies warm without making them sweat.

From 3 to 6 months: first dresses and dungarees
For girls, the first dresses arrive alongside rompers: pleated velvet skirts, warm-knit dresses with tartan, and little dresses in warm cotton check. For boys, the new arrival is dungarees, including ceremony versions with a shirt, together with outfits in velvet, warm cotton or warm knit.
If you go for a dress, think about socks or tights straight away, as her legs will be bare. Dungarees, on the other hand, are worn over a shirt or top: check the product page to see what's included.

From 6 to 12 months: dresses and ceremony outfits
Towards the first birthday, girls' options shift mainly to dresses: velvet with flowers, velvet and tulle, tartan with a blouse. For boys there are outfits, dungarees and ceremony outfits, some of them three-piece. Sartoria dei Piccoli does green tartan for both girls and boys: handy if there are siblings or cousins at the table to dress in matching tones. For coordinating colours between siblings, there's a dedicated guide.

What should you watch out for with bows, ribbons and coats?
Christmas clothes have more details than everyday ones: bows, collars, lace, sashes. According to guidance from paediatricians and health services, a few quick checks before you head out are all it takes.
- Ribbons and ties: no ribbons or ties that could knot or wrap around the neck, and nothing tied tightly around the arms, legs or neck (AAP).
- Dangling decorations: if a ribbon or decoration is hanging loose or coming off, remove it (Pregnancy, Birth and Baby). Before dressing your baby, run your fingers over bows and appliqués.
- In the car: no padded coat or pramsuit under the car seat harness. Strap your baby in wearing thin layers, do the pinch test on the harness strap and put the baby blanket or coat over the straps (AAP). An approved car seat suited to your baby's weight and height is needed even for a short journey, as the Italian Ministry of Health (Ministero della Salute) points out.
- As soon as you get indoors: take off the hat and any extra layers, even if your baby is asleep (NHS). To check whether they're too hot, feel their chest or the back of their neck: cool hands and feet are normal. One layer more than an adult is enough (AAP).
- If your baby falls asleep in the car seat or pushchair, move them to a firm, flat surface on their back as soon as you can (AAP).
General information, not medical advice: if you have any concerns about your baby, ask your paediatrician.
Do you need socks or tights with a Christmas dress?
With a dress, the legs are left bare, and in winter the AAP recommends socks, a hat and mittens when it's cold (AAP). Socks and tights are also needed with a shorts outfit. When choosing them, check there are no loops or loose threads inside that could wrap around little fingers or toes: Pregnancy, Birth and Baby recommends this, and it applies to mittens and bootees too.

To finish, booties or soft cot shoes, and a hat for the journey – to come off as soon as you're indoors.
What if the Christmas outfit is a gift?
Babies grow quickly in their first year, which is why Pregnancy, Birth and Baby suggests buying only a few items in each size. For the festive season, one well-chosen piece is enough. If you don't know the size, message us on WhatsApp, Monday to Saturday, 9am–1pm and 4pm–8pm, with the baby's age, height and weight. If you'd rather give a gift that doesn't depend on size, you'll find some ideas in what to give a newborn when you don't know the size.
Returns are accepted within 14 days of delivery, for items that are unworn, unwashed and with their tags attached. To plan the whole day, from morning to evening, see our guide on what your baby should wear for their first Christmas.
