The three-piece set that turns your little one’s first birthday into a moment nobody will forget.A first birthday only happens once, and this outfit is designed to make it look exactly as magical as it should. The Unicorn One Baby Girl First Birthday Outfit Set comes complete with a unicorn print romper, a multi-layered tutu skirt, and a matching flower headband. Everything you need is straight out of the box. At just £16.99, it is one of the best-value first birthday sets around.
Available in Pastel Rainbow (pink, purple, and blue layers with a gold glitter unicorn print) and Soft Pink (all pink tutu with a silver unicorn print), both versions are built for photos, parties, and the all-important cake smash.

What’s Included in the Set

2
Tutu Skirt
Multi-layered tulle with bow and pearl centrepiece
3
Flower Headband
Matching floral headband on a gold elastic band
Key Features
Unicorn “ONE” Print
The romper features a glitter unicorn face with eyelash detail and the word “ONE” printed at the centre. Gold glitter on the rainbow version, silver on the pink version.
3D Floral Embellishment
Delicate fabric flowers with pearl bead centres are attached to the romper around the unicorn print, adding texture and a boutique-quality finish.
Soft Cotton Romper
Made from a soft cotton blend that is gentle against baby’s skin. The bodysuit style makes nappy changes easy without removing the whole outfit.
Fluffy Tutu Skirt
Multiple layers of soft tulle give the skirt real volume and that full princess effect. A satin bow with a pearl bead sits at the front waistband.
Matching Headband
A flower headband on a gold elastic band completes the look. Coordinated to the outfit so everything works together in photos straight away.
Fully Lined Skirt
The tutu skirt is fully lined for added comfort and volume. Baby can sit, crawl, and move freely without the netting being scratchy against skin.
Available Colours
Both versions are equally beautiful. The Pastel Rainbow option has a more vibrant, multi-coloured look that suits unicorn and rainbow-themed parties. The Soft Pink option is a more classic, coordinated choice that works across a wider range of party themes.
Please note: This outfit is available in one size only, designed to fit babies aged 12 months (size 80). Stock can sell through quickly around birthday season, so ordering in advance is always a good idea.

Frequently Asked Questions
Does this outfit only come in one size?
Yes. This set is designed specifically for babies aged 12 months (size 80). It is a “first birthday” outfit, so it is made to fit the typical size for a one-year-old. If you are unsure whether size 80 will fit your baby, check the measurements in the size chart above or contact us directly and we will help.
Is the tutu skirt scratchy against baby’s skin?
No. The skirt is fully lined, which means the tulle layers sit over a smooth inner lining rather than directly against baby’s skin. This makes it comfortable for extended wear throughout a party or photoshoot.
Is this outfit good for a cake smash photoshoot?
Yes, it is one of the most popular uses for this set. The outfit is lightweight and easy to move in, and the colours photograph beautifully. The headband stays in place well, and the full tutu creates great visual impact in photos. Many parents buy two in case one gets messy mid-shoot.
What is the difference between the Pastel Rainbow and Soft Pink versions?
The Pastel Rainbow version has a tutu skirt in pink, purple, and blue layers, with a gold glitter unicorn print on the romper. The Soft Pink version has an all-pink tutu and a silver unicorn print on the romper. Both come with a matching flower headband. Neither is more or less detailed. It simply comes down to your colour preference and party theme.
Can this be worn in winter?
Yes. The romper is soft enough to layer a long-sleeve vest or bodysuit underneath without losing the look of the print from the front. A warm jacket or cardigan over the top will keep baby cosy in colder weather. The tutu skirt is also fully lined, which adds a little warmth around the waist and bottom.
How long does UK delivery take?
Standard UK delivery is estimated at 3 to 10 working days. Orders over £13 qualify for free UK delivery, which this outfit covers on its own at £16.99. For full postage details, visit our postage and returns page.
Is this a good gift for a baby’s first birthday?
It is one of the most thoughtful gifts you can give. It is practical, photo-ready, and completely ready to wear straight from the box. At £16.99 for a three-piece set, it looks and feels far more expensive than the price suggests. Many family members and godparents choose this as their go-to first birthday gift.
