Find Her First Birthday Outfit
Whether you’re planning a family gathering or a themed party, start with a first birthday outfit that suits the celebration and allows your little one to move comfortably. Explore Ellie Ellie’s dresses and baby rompers, from pink and ivory styles to floral embroidery, bows and layered tulle.
For a coordinated look, choose accessories that complement the outfit’s colour and details. Keep her comfort in mind throughout the day, especially when she’ll be sitting, crawling or taking her first steps.
Choose a Look for Her Birthday Theme
Pink, white and ivory offer a starting point for many birthday themes. For a strawberry celebration, explore our Berry First Birthday Dress. For a fairy-inspired look, discover floral embroidery in our Fairy Bloom Baby Romper.

Choosing the Right Size and Style
Choose her size using the measurements listed for the individual garment, rather than age alone. Compare the size guide with her current measurements and allow for comfortable movement. Our dress size chart is a useful starting point.
Consider the season, venue and activities when choosing a style. For warm-weather celebrations, check fabric and lining details; for cooler days, consider sleeves or a coordinating layer. If a cake smash is part of the plan, decide whether you’d like a separate outfit for the messy photographs.
First Birthday Outfit FAQs
Should I choose a dress or a romper for her first birthday?
Either can work beautifully. A dress offers a classic party look, while a romper is another option for a baby’s birthday outfit. Compare the individual style’s fit, lining and fastenings, and choose something that lets her sit and move comfortably.
What size should I buy for a baby turning one?
Use her current measurements and the individual product’s size guide. Age labels are a starting point, as babies’ measurements and garment fits vary. If the celebration is still some time away, check her measurements again closer to ordering.
Can she wear her birthday dress for a cake smash?
You can choose to use her party dress or change her into a separate outfit. Icing can mark fabrics and decorative details, so check the product’s care instructions before deciding. See our care guide for general guidance.
How early should I order a first birthday outfit?
Allow time for order processing, delivery and trying the outfit on before the celebration. Check whether your chosen item is in stock or on pre-order, and review our shipping policy for delivery information.
Can she wear the outfit again after her birthday?
Depending on its style and fit, the outfit may also suit family photographs, weddings or other celebrations. Changing the accessories can give the same dress a different look.
