Princess Estelle of Sweden in national costume in 2015
National Day in Sweden means lots of things and among them are lots of royal appearances. Today, Prince Carl Philip and Princess Sofia will take on the duty of opening the castle while the whole family will join in celebrations. And we usually get a photo of Estelle in national costume. It's a big day.

The photos usually come early on National Day and last year the little princess looked very grown up as she posed in the gardens of her home at the Haga Palace.

So we can confidently expect another image of Sweden's future queen in her country's national dress to mark national day this year. Whether Prince Oscar joins her in the photos remains to be seen. But as Sweden's big day gets under way, there's plenty of royal sightings to look forward to.
