This Rosalina costume turns your daughter into the galaxy's own princess for Book Week 2026 – a floor-length teal gown with an optional long blonde wig, crown, star wand and jewellery set, sold in kids sizes 110-160cm.
The dress arrives as a complete princess gown – off-shoulder neckline, long sleeves with delicate lace-trim cuffs and a flowing floor-length skirt – cut from soft, lightweight polyester so it stays comfortable through a parade, a class party and an afternoon of twirling. Choose the package that suits: the dress on its own, or bundles that add the long blonde wig and the four-piece accessory set so nothing needs hunting down separately the night before.

Sizing tip: if your daughter measures between two height bands, or she will wear a thermal underneath on a cold August parade morning, choose the larger size. A floor-length gown with a little extra room twirls and photographs beautifully, while a snug one starts to pull at the shoulders before the parade is over.
Why Parents Choose This Rosalina Costume
Everything in one box - the full bundle covers dress, wig, crown, star wand and jewellery, so there are no separate accessory purchases to chase down in August.
Instantly recognisable - the teal gown and star wand read as the galaxy princess from across the playground, with no explaining needed at the parade microphone.
Comfortable for a full school day - soft, lightweight polyester moves with her instead of scratching or overheating between the parade and the classroom.
Five package options - buy only what you need, from the wig alone to the complete set, rather than paying again for pieces you already own.
Worn long after Book Week - princess dress-ups come around constantly, so the gown returns for birthdays, Halloween and everyday imaginative play.
Fabric & Care
The gown is cut from soft, lightweight polyester chosen for comfort rather than stiffness, finished with delicate lace trim at the cuffs. That construction is what lets a child sit cross-legged at assembly, run at lunch and still look parade-ready for the afternoon photo.
Hand wash in cold water, do not bleach, and hang to air dry naturally rather than tumble drying. Avoid ironing directly over the lace trim and embellishments. Please allow 1-3 cm variance in stated measurements, as each piece is cut and sewn individually.
Book Week and Party Styling Ideas
Rosalina comes from the Super Mario games, where she is the keeper of a storybook – in Super Mario Galaxy she reads her own story aloud, chapter by chapter, to the little star Lumas in her observatory library. That gives this costume a genuinely bookish hook: pair it with one of the Super Mario storybooks, annuals or character guides in print, bring the book along on the day, and your daughter has a character, a story and a library connection to name when asked.
For styling, silver or pale ballet flats sit best under the floor-length hem, and star-shaped hair clips suit girls wearing their own hair instead of the wig. Seat the crown just forward on the head so it shows in photographs, and keep the star wand in hand for the parade. In a group, this costume lines up naturally beside Mario, Luigi and Princess Peach outfits so a set of friends arrives as one clear theme.
Frequently Asked Questions
What is in the accessory set? A decorative crown, star wand, star necklace and matching earrings. The set is included only with the package options that specifically list it.
What sizes does it come in? Kids sizes 110-160, chosen by your child's height in centimetres. If she measures between two bands, take the larger size.
Does the wig fit all kids? The long blonde wig comes in one size and is included in the Dress + Wig, full bundle and Wig Only options.
Can she wear it for the whole school day? Yes. The soft, lightweight polyester is made for movement, so it stays comfortable from the morning parade through to the afternoon.
Will it arrive in time for Book Week? We dispatch quickly from Sydney and most Australian metro orders arrive within a few business days. Order as early as you can in the lead-up to Book Week, as August is our busiest period and courier networks slow under the volume.
