Girls Rainbow Magic Unicorn Dress-Up Set

Complete 3-Piece Girls Unicorn Fancy Dress with Wings and Headband for Ages 1 to 12 Years

Looking for a girls unicorn costume that arrives complete and ready to wear? This Rainbow Magic Unicorn Dress-Up Set gives you everything in one box: a full rainbow pastel tutu dress, a pair of shimmery unicorn wings, and a matching unicorn horn headband. No separate accessory hunts, no mismatched colours, no last-minute stress.

The dress features a soft white crochet-style bodice decorated with colourful flower blooms and sweet embroidered eyelashes, giving it that instantly recognisable unicorn face design. Below the bodice, multiple layers of soft tulle fall into a full, knee-length skirt in a mix of pastel pink, lilac purple, sky blue, mint green, and white. At the back, wide satin straps tie into a neat bow, making it both adjustable and simple to put on and take off.

Whether you need a unicorn birthday outfit for a party, a World Book Day costume, or something for imaginative play at home, this set covers every occasion. It fits girls from age 1 right through to age 12, so it works across a wide range without any size guesswork.

What Is Included in the Set

Everything arrives together in one package. There is nothing extra to purchase separately.

Colours in This Dress

The rainbow pastel colour palette is one of the things that makes this dress stand out. Rather than a single solid colour, the tulle skirt blends five distinct pastel shades into one layered, flowing skirt. This creates a soft, dreamy rainbow effect when the skirt moves, which is especially impressive in photos and on video.

The bodice is white with colourful flower embellishments in pink, coral, teal, and yellow, picking up threads from the skirt palette and tying the whole look together. The headband follows the same pastel theme, with a gold glitter horn and floral detailing in complementary shades.

The wings are available in two finishes. The Rainbow Metallic wings use a bold, shimmery multi-toned gradient across each feather. The Pastel Iridescent wings have a softer, lighter finish that shifts between pastel hues as the light catches them. Both are designed to work with the dress rather than overpower it.

Design Details Worth Knowing

The Bodice

The top half of the dress uses a soft, elasticated crochet mesh that stretches to fit different body shapes without feeling tight. There are no buttons, zippers, or fiddly fastenings to deal with, so it pulls on easily, which is a real advantage when dressing younger children who do not like to stand still. The front is adorned with three large handcrafted flowers in pink, coral, and teal, with a yellow bud alongside them. Just below the flowers, two embroidered eyelashes create the unicorn’s sleepy face, which is one of the most distinctive features of this style. Glitter unicorn ears peek out from the shoulder straps, adding detail even from behind.

The Skirt

The tulle skirt is made from multiple layers of soft mesh, which gives it that full, voluminous shape without being stiff or scratchy. Each layer is cut to fall at knee length, creating a princess silhouette that holds its shape throughout a party. The colour arrangement of the tulle layers means the dress looks different from every angle, with the pastel shades blending and shifting as the skirt moves. This layered construction also means the skirt has good body and does not flatten easily, even after hours of wear.

The Back

At the back, the wide satin shoulder straps cross over and tie into a large bow at the waist. This gives the dress an elegant, finished look from behind while also making it fully adjustable. If your child is between sizes, the bow can simply be tied tighter or left a little looser for a better fit. The crochet back panel continues the white mesh design of the front bodice, keeping the look consistent all the way around.

The Headband

The unicorn horn headband sits comfortably across the head and features a gold spiral horn at the centre, flanked by two glitter-tipped unicorn ears. Small decorative flowers in pastel shades are clustered at the base of the horn, matching the floral detail on the dress. It is lightweight and suitable for extended wear without becoming uncomfortable.

Why This Set Works So Well

A common issue with unicorn dress sets is that the accessories do not quite match the dress: slightly different shades, a headband that clips awkwardly, or wings that are oversized and uncomfortable for younger children. This set is designed as a complete package, so the colours across the dress, wings, and headband are all drawn from the same pastel rainbow palette. Everything coordinates without any extra effort on your part.

The stretch crochet bodice removes the need for any fiddly buttons or zippers, which makes it genuinely quick to get on and off. Parents of younger children will appreciate this during a busy party morning. The satin bow at the back is both practical and decorative, allowing for an adjustable fit without compromising the look of the dress from behind.

The multilayer tulle skirt holds its shape well throughout the day. Tulle is a lightweight fabric that does not crease easily, and the layered construction means the skirt retains its volume even after several hours of active wear. For more background on why tulle works so well for dress-up outfits, see our article on what you need to know about tulle.

This is also one of the most versatile fancy dress options available for girls in this age range. Rather than a single-occasion costume, the pastel rainbow colour palette and princess silhouette mean the dress works equally well for a unicorn birthday party, a World Book Day character, a Halloween costume, and a cake smash session. You will get multiple uses out of this set rather than one.
