When the occasion calls for something truly special, Itty Bitty’s baby girl special occasion dresses collection delivers. From delicate christening gowns and formal wedding guest dresses to show-stopping birthday party dresses and festive occasion wear, every piece in our boutique collection is chosen for its quality, craftsmanship, and the way it makes your little girl look and feel extraordinary.
Types of Baby Girl Special Occasion Dresses
Christening dresses: The most formal of all baby girl occasion dresses. Traditional christening gowns are long, in ivory or white, with lace trim, embroidery, and pearl detailing. Contemporary christening dresses are shorter with tulle skirts and satin sashes. Both styles are available in our dedicated christening dresses collection.
Wedding guest dresses: For a wedding, a beautiful occasion dress in a complementary colour — blush pink, ivory, champagne, sage green, or navy — is the perfect choice. Look for dresses with embellishments, lace overlays, or satin sashes that feel formal without being uncomfortable for a baby to wear for a full day.
Birthday party dresses: First birthdays and milestone birthday parties call for a dress that photographs beautifully and makes a statement. Tutu dresses, embellished satin dresses, and smocked occasion dresses are all popular choices. See our dedicated baby party dresses page for more inspiration.
Formal family occasion dresses: Naming ceremonies, family portraits, religious occasions, and formal family gatherings all call for something special. A beautifully made boutique occasion dress in a classic colour and style is always the right choice for these occasions.
What to Look for in a Baby Girl Occasion Dress
The best special occasion dresses for baby girls balance beauty with practicality. Here is what to look for:
Soft cotton lining: This is the most important feature. Tulle, satin, and lace can be scratchy against a baby’s sensitive skin. Always check that the dress has a soft cotton lining before buying — this is what separates a genuinely well-made boutique dress from a cheaper alternative.
Secure fastenings: Buttons, poppers, and zip fastenings at the back or crotch make dressing and nappy changes much easier. Avoid dresses that require complete removal for every nappy change.
The right size: For occasion dresses that need to fit well on a specific day, buy to your baby’s current measurements rather than sizing up. Use our baby clothes sizes guide to find the right fit.
Completing the Special Occasion Look
A beautiful occasion dress deserves the right accessories. For christenings and formal occasions, white or ivory tights, a matching headband or bonnet, and soft occasion shoes or booties complete the look. For birthday parties and less formal occasions, embellished sandals and a matching bow or headband are perfect.

What is the difference between a christening dress and a special occasion dress?
A christening dress is specifically designed for a christening ceremony — typically long, in ivory or white, with traditional detailing. A special occasion dress is a broader category covering any formal or semi-formal event including weddings, birthday parties, and family gatherings. Many christening dresses can also be worn for other formal occasions.
What age do your special occasion dresses go up to?
Our baby girl special occasion dresses cover sizes from newborn through to 24 months. For older children, our kids boutique clothes range includes occasion wear up to age 8.
Do you offer next-day delivery on occasion dresses?
Yes — express next-day delivery is available at checkout. Standard free delivery applies to all orders over £50.
