Deep Purple Sequin Girls Mermaid Birthday Dress and Headband Set. Bold purple sequin bodice, real starfish waist detail, ribbon streamers, deep purple and teal tulle skirt. Sizes 1 to 12 years for £28.99.
Where the pink version of this sequin mermaid dress is soft and pastel, the Deep Purple version is bold and vivid. The sequin bodice is a deep, saturated purple that catches light with intensity, the tulle skirt combines deep purple with bright teal and soft lilac, and the waist detail uses real natural starfish rather than glitter versions. It is the same high-quality construction and the same impressive size range up to age 12, but with a colour palette that makes a much stronger visual statement.
Three satin ribbon bows in teal and purple sit at the waistline, each centred with a real starfish, and long satin ribbon streamers in matching colours hang down through the front of the skirt for a flowing, dramatic effect. The complete set includes a matching headband with rose gold glitter details and blue fabric roses. At £28.99.
How This Differs from the Pink Sequin Version

- 1 x mermaid birthday dress with deep purple sequin bodice, three satin ribbon bows with real starfish accents and hanging ribbon streamers at the waist, deep purple and teal tulle skirt, wide purple satin shoulder straps

The Dress in Detail
The Purple Sequin Bodice
The entire front and sides of the bodice are covered in deep purple flat sequins that shift between purple and violet as they catch the light. It is a richer, more saturated look than the iridescent fish scale fabric used on the halter-neck mermaid sets in the range, and it photographs with striking intensity. The back of the bodice is covered in smooth purple satin rather than sequins, giving a clean, structured finish from behind. Wide purple satin shoulder straps sit over the shoulders for a secure, comfortable fit throughout a full party.
The Starfish and Ribbon Waist Detail
At the waistline, three satin ribbon bows are positioned across the front. The outer two are purple satin and the centre one is teal. Each bow has a real, natural starfish sitting at its centre, which is a tactile, organic detail that immediately stands out from the glitter or plastic alternatives on other mermaid dresses. From each bow, long satin ribbon streamers in matching purple and teal hang down through the tulle layers of the skirt, adding movement and a flowing, dramatic element every time the dress is in motion.
The Tulle Skirt
The skirt is built from multiple layers of tulle in deep purple, bright teal, and soft lilac. The colours are more saturated and vivid than the pastel palette of the pink sequin version, which gives the whole dress a bolder, more striking appearance. The skirt falls to approximately knee length and holds its full, bouncy volume throughout the day. A purple rhinestone trim runs along the waistband, adding a fine sparkle at the transition between bodice and skirt.
The Colour
This colour combination sits firmly in the classic deep-sea mermaid palette. The contrast between the vivid purple and bright teal is striking without being jarring, and the colours photograph very well together.

Who Is This Dress For?
Parents who want a bolder, more vivid mermaid look: If the pastel palette of the other sets feels too soft and you want something that commands attention at a party, this is the right choice. The deep purple and teal combination is one of the most striking in the entire mermaid range and it looks particularly impressive under the kind of lighting typical at birthday parties and staged photoshoots. Our birthday outfit ideas guide has more suggestions for styling the full look.
Parents of girls aged 1 to 12 who need the extended size range: This dress goes up to 3XL for girls aged 11 to 12 years, making it one of only two mermaid dresses in the range that caters for this age group. For Halloween costume planning, our Halloween costume ideas guide has more tips on putting together a complete look.
Parents who want a machine washable party dress: Both sequin mermaid dresses in the range are machine washable as well as hand wash compatible, which makes them more practical for repeated wear than the halter-neck tutu sets. Browse our girls special occasion wear collection for more ideas.
