This traditional outfit is known as a kira and Kate's came in purple and blue with a white coat with delicate embroidery detail.
The material seen in the skirt, which wraps around to produce a slit, was ordered from Bhutan and made by a lady called Mrs Kelzan Welmo. It's a beautiful set of colours with the deep purple off set by a bright jewel blue that really catches the eye.
The kira is traditionally worn with a jacket and this one is a winner. It's actually a cape which Kate has added a belt to. The unusual sleeves suit the Duchess of Cambridge while the pretty patterning on it is fabulous on Kate. This is an outfit to remember and one that won't be forgotten in a hurry.
Kate had begun the day in an Emilia Wickstead coat that we saw in 2012 and which is as smart and go with anything as it was then.
The colour was good for the start of the tour but it's not really a remarkable or stand out look. It's just very elegant and does the job.
Kate chose a Tory Burch evening gown for her dinner with the King and Queen of Bhutan at the end of her first day in the country.
This actually has the potential to be a wow dress and I expect to see it several times again in the future as it's got the potential to be an eye catcher every single time. The addition of the bright orange wrap was a brilliant choice. A Kate classic in the making.
The geometric print gives way to a slit on either side and we even got unusual shoes - strappy sandals which looked great and which need to make more of an appearance. Altogether, another great look but it was never going to win gold medal on the day Kate wore a kira.
