That's quite a bit of casual bunning,even for an almost-royal. The fact that she wears it exclusively with what might best be described as"office manager"dresses allows for the messiness. Which means you,too,can wear it to the office,or a family wedding. The question now becomes:how?

For the answer,we turned to celebrity stylist and hairdresser Anthony Nader,from Raw Hair in Sydney's Surry Hills.

Nader recommends you begin by making sure you have second day hair."Your hair will be better off left on the dirtier side. If you strands are too clean and soft at the moment,give them a quick once over with a dry texture spray,likeMuk's sea salt spray – over the root area and massage the product through."

"Lightly brush the product through with a Mason Pearson brush as this will distribute nice and evenly from mid-lengths to ends.

"Next,tilt your head back and scrape your hair from the hairline back to the nape area into a bun that’s just below your crown area. Tie this up into a twisted knot and secure with bobby pins.

"Pull loose the shorter pieces framing the face as this gives you the modern,current edge that is required for this royal look.

"Make sure that you have shorter pieces framing the face for this. If your hair is one length,it won’t do you any favours,as you need shorter pieces to soften the look of what we’re trying to achieve. Also,you don’t need to go overboard with smoothing over the hair shape,as that’s going to look way too formal. Keep the texture piecey and disheveled to nail this royal up-do."

There you have it. The perfect casual bun to wear to an upcoming wedding – perhaps even your own.

*Emotionally stable i.e. not hate reading this because you consider yourself somehow superior for looking down on a woman in her mid-thirties.
