High-Low Unicorn Dress with Pastel Rainbow Tiered Train and Large Back Bow • 7 Set Options • Ages 2 to 10 Years • Unicorn Parties, World Book Day, Halloween and Photoshoots
A Girls Unicorn Dress That Makes Every Entrance Unforgettable
Most unicorn party dresses photograph well from the front. The Seraphina Dress photographs brilliantly from every angle. The front is short, sitting above the knee, but the back falls into a long tiered rainbow train that cascades through blue, pink, lilac and purple layers all the way to the floor. When she walks into a room or twirls on a dance floor, the train moves and fans out behind her in a way that stops people in their tracks.
The bodice is white satin with tulle ruffle flutter sleeves and an open back that fastens with a button closure. A large pastel bow sits at the back waist where the tiered train begins. The front of the skirt features unicorn and star embroidery that finishes the look with a detail girls aged 2 to 10 genuinely love.
What makes this product stand out from every other unicorn dress in this price range is the flexibility of the set options. You can buy the dress alone from £28, or build the full costume by adding metallic rainbow wings, a gold unicorn headband and a blue-purple-pink wavy wig.

Choose Your Set Option
Select the combination that suits your budget and occasion from the dropdown when adding to basket. The dress is the same across all options.
High-Low Rainbow Train
The front skirt sits above the knee while the back falls into a long multi-tiered train in pastel rainbow layers. The effect in motion is genuinely striking and photographs beautifully from behind.
Large Back Bow
A generous pastel bow sits at the back waist where the train begins. It is one of the most photographed details on this dress and gives it a formal, occasion-wear feel from behind.
Mix and Match Accessories
Wings, a gold unicorn headband and a full-length wavy wig are available as add-ons in any combination. Start with the dress and build the costume to suit your budget.

About the Optional Accessories
Gold Unicorn Headband
A gold glitter unicorn horn on a hairband with cat-style ears and floral detail at the base. Sits comfortably over most hairstyles and is included in the headband, wings + headband, and full set options.
Rainbow Metallic Wings
Detachable metallic feather-style wings in rainbow shades. They attach at the back of the dress and can be removed for sitting, eating or travel. Included in the wings, wings + headband, wings + wig, and full set options.
Unicorn Wig
A long wavy wig in blue, purple and pink with its own silver unicorn horn headband attached. Transforms the look into a full character costume for World Book Day, Halloween or cosplay. Included in the wig, wings + wig, and full set options.
If you are ordering for World Book Day or Halloween, the full set option gives the most complete costume. For a birthday party where she will be wearing the outfit all day, the wings + headband option is often the most practical.
Perfect For
The high-low train makes this dress particularly popular for professional photoshoots. Photographers specifically seek out dresses with a long trailing element because they create movement and drama in images. The outdoor shot in the product images shows exactly how the train looks in natural light during a garden photoshoot and the result is genuinely stunning.
For World Book Day and Halloween, the full set with wings, wig and headband gives a complete character costume that rivals far more expensive options. For a birthday party, the dress alone or with wings is usually the most practical choice for a child who needs to eat, sit and run around.

Styling Tips
Shoes: White or silver ballet flats are the most natural choice across all set options. Sparkly shoes in white or pastel pink add extra glamour for a party. For outdoor photoshoots, bare feet or simple sandals keep the focus entirely on the dress.
Wings vs no wings: The detachable wings add significant visual impact but can make sitting at a table difficult for younger children. If the event involves a sit-down meal, consider removing the wings for that portion of the day and re-attaching them for photos and play.
Cooler weather: A plain white or pale blue cardigan worn underneath the dress keeps her warm without hiding the open back bow or the ruffle sleeves. For a lace bolero jacket, choose white or ivory to stay within the colour palette.
Size Guide
Sizes are based on height and age. Always measure your child’s chest and compare to the table below rather than ordering by age alone. If she is between sizes, choose the larger one. Visit our guide on how to take measurements for children’s clothes and the full girls size guide for more detail.
All measurements in centimetres. Please allow +/- 3 cm variance. The dress length refers to the short front skirt length. The train at the back is longer.
| Size Label | Age | Chest (cm) | Front Length (cm) | Height (cm) |
|---|---|---|---|---|
| 100 | 2–3 years | 56 | 80 | 85–95 |
| 110 | 4 years | 60 | 90 | 95–105 |
| 120 | 5 years | 64 | 100 | 105–115 |
| 130 | 6 years | 68 | 110 | 115–125 |
| 140 | 7–8 years | 72 | 120 | 125–135 |

Care Instructions
Hand wash the dress in cool water with a mild detergent. Do not wring the tulle train as this can flatten the layers. Hang to dry and shake the tulle gently once dry to restore volume. The wings should be spot cleaned only. The wig can be gently combed and stored flat when not in use. For garment care guidance, see our article on how to care for kids dresses and our guide on how to care for tulle.
Frequently Asked Questions
How long is the train at the back of the dress?
The train length increases with each size. For the smallest size (age 2 to 3), the total front length is approximately 80 cm and the train extends further behind. For the largest size (age 9 to 10), the front length is approximately 130 cm with a longer train at the back. Please refer to the size guide table above for the front skirt length per size. Contact us if you need the specific train length for a particular size.
Can the wings be removed and reattached during the day?
Yes. The wings are detachable and can be removed and reattached. This is useful for events where she needs to sit at a table, travel in a car or take a break from wearing them. The dress looks complete with or without the wings attached.
What is the difference between the headband and the wig?
The headband is a gold glitter unicorn horn on a hairband with cat-style ears and a flower at the base. It sits on top of her own hair. The wig is a full-length wavy hairpiece in blue, purple and pink that goes over her own hair and has its own silver unicorn horn attached. The wig creates a more complete character transformation and is particularly effective for Halloween, World Book Day and cosplay events. The headband is better suited to all-day party wear where a full wig might become uncomfortable.
Is this dress suitable for a professional photoshoot?
Yes, and it is one of the most popular choices for this use. The tiered rainbow train creates natural movement and dramatic visual interest in photographs, particularly from behind. The outdoor lifestyle image in the product photos shows exactly how it looks in a garden setting. The wings add extra visual impact for studio shoots. Most photographers find the dress works beautifully with or without accessories.
Which set option is best for a birthday party?
For a birthday party, the Dress + Wings + Headband option is the most popular choice. The wings and headband give a full unicorn look without the discomfort of a full wig over several hours. The wings can be removed for sitting and eating and reattached for photos. The full set with the wig is better suited to shorter events like photoshoots, World Book Day or Halloween where she is not wearing it all day.
Is this suitable for World Book Day?
Yes. The Seraphina Dress is one of the most recognisable unicorn costumes available at this price point. The full set with wings, wig and headband creates a complete character costume. Because the dress is available in pieces you can also choose just the elements your child’s school allows, as some schools have restrictions on wings or wigs for practical reasons.
How do I choose the right size?
Measure your child’s chest and check her height against the size guide table above. Size labels 100 through 150 correspond to approximate heights in centimetres. If she is between sizes or growing quickly, go up. Contact us before ordering if you would like help choosing.
How long does delivery take?
Standard delivery is between 5 and 20 working days. Free UK delivery applies to orders over £13. If you are ordering for a specific event such as a birthday party or World Book Day, place your order as early as possible to allow plenty of time for delivery and fitting.
