Rosalina costume size guide (girls 110–160)
Available in sizes 110, 120, 130, 140, 150 and 160 (plus a One Size option), this costume is designed to fit children roughly 100–160 cm tall — around ages 4 to 12. For the best fit, measure your child's height and compare it to the size-chart image before ordering. If your child is between two sizes, we recommend sizing up for room to move.
Perfect for Book Week, cosplay and princess parties
This kids' princess dress is a go-to for so many occasions: Book Week and book-character parades, video-game and Super Mario princess cosplay, princess birthday parties, Halloween and trick-or-treating, school concerts and plays, and everyday imaginative dress-up. It also pairs beautifully with Princess Peach and Daisy costumes if you're planning a group Super Mario princess theme.
Fabric & care
The gown is made from smooth, soft, comfortable polyester chosen for rich colour and easy movement. To keep it looking its best, we recommend a gentle cold hand-wash and hanging to air-dry — avoid tumble drying and don't iron directly over any trims or embellishments.
Frequently asked questions
Does this Rosalina costume come with a wig?
It can. Choose the "Dress + Accessory Set + Wig" or "Dress + Wig" package to include the signature long blonde wig, or select "Wig Only" to add it to a gown you already own.
What accessories are included?
The accessory set features a crown/tiara, a star wand and a star necklace with matching earrings. The exact items depend on the package option you choose at checkout.
What size should I order?
Sizes run from 110 to 160 to fit heights of roughly 100–160 cm (about ages 4–12). Measure your child's height and check the size chart; if they're between sizes, size up.
Is this a Princess Peach costume?
This is a Rosalina costume — the galaxy princess in her signature teal gown, rather than Princess Peach's pink dress. It's a popular pick for Super Mario group themes alongside Princess Peach and Daisy costumes.
Is it suitable for Book Week?
Yes — a flowing princess gown is a classic Book Week and dress-up parade choice, and the optional wig and crown make it extra memorable.
