Crown Princess Victoria, Prince Daniel and Princess Estelle on her christening day in 2012
There's a good chance Victoria will be in blue for her little boy's big day as she chose pink for the christening of her daughter, Princess Estelle, on May 22nd 2012.
The new mum chose a fitted dusky pink dress with plenty of detail at the top, perhaps knowing that juggling a three month old means lots of photos of arms.
There was a lovely lace effect at the top of Victoria's dress and the cap sleeves were just the right length to keep things simple as she and Prince Daniel passed their daughter between them to keep her happy during her first big royal event.
Victoria chose a small matching hat with pink flower details at the top and at the back to complete her first royal christening look as a mummy.
It was palest pink for Princess Madeleine as well when she had her first child, Princess Leonore, christened on her first wedding anniversary, June 8th 2014. So far, so colour co-ordinated.
There was lace involved in this one too - a lot more for this new mum though than Victoria had chosen. Madeleine's dress was completely covered in palest pink lace.
It was a summer's day so this new mummy also chose short sleeves with a much shorter skirt than big sister had opted for when christening her own first born.
Madeleine went for a very unusual hat which was involved symmetrical clusters holding in place a large veil which covered her face. It added another layer of lightness to this very summery outfit.
Again, there was no traditional hat for Madeleine who this time round opted for a flourish of curled ribbons in brightest purple which picked out the dominant colour on her coat.
But despite the lack of a solid blue outfit for this christening there was enough of a hint of that colour to see a pattern. Pink for a girl, blue for a boy. Short sleeves for summer and no big picture hats. We'll know what Victoria wore for Oscar's christening tomorrow but expect blue, cap sleeves and an only just there piece of headwear. Can't wait.
