Unicorn dressing is one of the most enduring party themes for girls, and this 3-piece set is the most complete and well-executed version of it that we stock. The dress itself is a full-length ball gown with a tiered rainbow tulle skirt. The bodice carries an embroidered unicorn face with gold thread, closed eyes and delicate eyelashes, surrounded by a cluster of 3D pastel flowers with pearl and crystal centres. The construction quality on those flowers alone sets this apart from most unicorn dresses at this price point.

The set is complete from head to toe. The iridescent rainbow metallic wings attach at the back shoulders of the dress and spread wide for an instant transformation moment that never fails to get a reaction. The gold unicorn horn headband with pink tulle at the base completes the look. Three pieces, all included, all coordinated.

Available in pink, white and purple rainbow versions, with sizes from age 4 to age 12 years. The skirt uses four tiered tulle layers, each edged with a ribbon trim in a different pastel colour, creating a rainbow effect that is visible from the front, the side and the back. At £29.99 for the complete 3-piece set this represents exceptional value for a dress of this embellishment level.


What Is Included

  • The Unicorn Princess Dress – full-length floor-length ball gown with unicorn embroidered bodice, 3D floral detail, four-tier rainbow tulle skirt, satin back bow and concealed zip.
  • Rainbow Fairy Wings – iridescent metallic wings in a rainbow scale/feather pattern that attach to the back of the dress. Worn as an accessory during the party and removable when not needed.
  • Unicorn Horn Headband – gold twisted horn with small unicorn ears and pink tulle at the base. Sits on the head as a headband to complete the unicorn transformation.

The Three Colour Options

Pink Rainbow

The pink version has a soft pink satin bodice and back panel, with a pink satin bow at the back waist. The four-tier tulle skirt moves through the rainbow in pastel pink, blue, lilac, yellow and green tones, with each tier edge trimmed in a contrasting pastel ribbon. The unicorn face on the bodice is embroidered in gold and surrounded by pastel flowers. The pink version is the most traditionally feminine and the most popular choice. It suits children who love a warm, rose-pink tone as the dominant colour of the dress.

White Rainbow

The white version has a clean white satin bodice and back panel with a white satin bow. The tulle skirt tiers move through the full rainbow palette against a lighter, more ethereal base, which makes the individual colours appear more luminous than on the pink or purple versions. The white is the most versatile of the three for occasions beyond a unicorn party, including formal celebrations, Easter and spring events. It is also the strongest choice for photography, as the white bodice provides maximum contrast for the embroidered unicorn detail and the pearl-centred flowers.

Purple Rainbow

The purple version has a soft lavender satin bodice and back panel with a purple satin bow. The rainbow tulle tiers appear slightly different against the purple base, with the cooler tones of blue and lilac appearing more prominently. The purple version has the most magical, fantasy-inspired feel of the three and suits children who specifically love purple or who identify with the more mystical side of unicorn mythology. It also works particularly well for evening and indoor party settings where the purple deepens beautifully under artificial light.


Design in Detail

The Embroidered Unicorn Bodice

The front bodice carries an embroidered unicorn face in gold thread. The design shows closed, dreaming eyes with long curled eyelashes and a small delicate nose, all outlined in warm gold. The embroidery continues with the suggestion of the unicorn’s cheeks and expression, creating a gentle, sweet face rather than a cartoon character.

Below the unicorn face, a cluster of five to six 3D fabric flowers in blue, pink, mint, yellow and lavender pastel shades are applied to the bodice. Each flower has a raised, dimensional petal structure and a centrepiece of small pearls and crystal rhinestones. These are not flat printed flowers or simple embroidery. They are individually crafted and have real physical depth and sparkle.

The Four-Tier Rainbow Tulle Skirt

The skirt is constructed in four distinct tiers, each layer progressively longer than the one above it, cascading from the high waist to the floor. Each tier is made from soft tulle in rainbow pastel tones, with the colours blending and layering across the tiers to create a full-spectrum rainbow effect. The edge of each tier is trimmed with a ribbon in a contrasting pastel colour, cream, pink, blue and pink again from top to bottom, which defines each layer and adds additional colour detail that is visible from the front, the side and particularly from the back.

The Front Overlay Panel

Over the main tiered skirt, a separate overlay panel of tulle is attached at the front waist. This creates a high-low effect where the front of the dress is slightly shorter and more structured at the front before the full tiered layers become visible below and behind. The overlay panel also gives the dress more volume and fullness at the front, contributing to the full princess ball gown silhouette.

The Rainbow Metallic Wings

The wings are constructed from metallic scale-shaped or feather-shaped sections in an iridescent rainbow palette, with colours shifting across the surface as the light changes. They attach at the back shoulders of the dress, spreading wide to give the full unicorn-angel visual effect. The wings are lightweight and designed to be worn during the party and removed when the child needs to sit comfortably for extended periods.

The Gold Unicorn Horn Headband

The headband carries a tall gold twisted horn at the centre, flanked by small unicorn ears. Pink tulle gathers at the base of the horn, creating a soft, cloud-like effect at the base of the horn. The headband sits securely on the head without needing to be fastened and is comfortable for extended wear throughout a party.

Size Guide

Available in sizes for ages 4 to 12 years. Measure your child’s chest and compare to the chart below. Always use measurements rather than age as the primary guide. For full measuring guidance, visit our girls clothing size guide.

Size (Age)Chest (cm)Dress Length (cm)Shoulder (cm)Height (cm)
3 to 4 years598523100 to 110
5 years639024110 to 120

9 to 10 years7510527140 to 150
11 to 12 years7911028150 to 160

Dress length is measured from the top of the neckline to the hem. The shoulder measurement is from shoulder tip to shoulder tip across the back. Please allow plus or minus 3cm due to manual measurement.

The size chart includes a size for 3 to 4 years, though the dress is listed for ages 4 to 12. If ordering for a young 4-year-old, use the 3-4 years row as the guide. If between sizes, order the larger for a more comfortable fit and to allow for growth. 1 inch = 2.54cm.

Frequently Asked Questions

Does the full 3-piece set come included in one order?

Yes. One order of this dress includes the full-length unicorn princess dress, the rainbow metallic fairy wings and the gold unicorn horn headband. All three pieces arrive together. Nothing else needs to be purchased to complete the outfit.

How do the wings attach to the dress?

The wings are designed to attach at the back shoulder area of the dress. They are detachable, meaning they can be removed when the child needs to sit down for extended periods, eat at a party table or travel in a car seat. For the wearing and dancing portions of a party, the wings attach securely and spread outward to create the full unicorn-angel visual effect.

Is this suitable for World Book Day?

Yes. Unicorns appear in a wide range of popular children’s books, and a unicorn princess costume is one of the most widely accepted and recognised World Book Day choices for girls in primary school. The dress is elaborate enough to be immediately recognisable as a unicorn costume without needing any additional explanation or prop. The full 3-piece set means the child has the headband and wings to complete the character immediately.

Can this be used as a Halloween costume?

Yes. A unicorn princess is one of the most popular non-scary Halloween costume choices for girls in the primary school age range, and the full-length ball gown with wings and horn creates a genuinely impressive costume that stands out on the doorstep. The rainbow tulle and metallic wings are striking enough to work well in evening and low-light Halloween settings.

What size should I order?

Use your child’s chest and height to find the correct size in the table above. The dress is a floor-length gown, so the height measurement is particularly important for ensuring the hem sits at the right length. If your child is between sizes, order the larger for a more comfortable fit. Our girls clothing size guide and children’s measurement guide explain how to measure accurately.

Which colour is most popular?

The pink version is consistently the most popular choice, as pink is the most strongly associated colour with unicorn aesthetics for most children. The white version is the most photogenic and the most versatile for occasions beyond a unicorn party. The purple version is favoured by children who specifically love purple and suits a slightly more mystical, magical interpretation of the unicorn theme. All three use the same rainbow tulle skirt and accessories, so the choice comes down purely to the base colour preference.

Is the dress suitable for a unicorn birthday party theme?

Yes, this is the ideal outfit for a unicorn-themed birthday party. The 3-piece set means the birthday girl is fully dressed as a unicorn princess from the moment she puts the outfit on, with no missing accessories. The floor-length ball gown silhouette gives her a genuinely different and more formal look than a standard unicorn fancy dress costume, which suits being the star of a birthday celebration.
