How to master the Royal updo, as seen on the Duchess of Sussex

Having taken some time off to enjoy her first summer at Balmoral, The Duchess of Sussex  appears to be 'back to work'. She made her debut at at the hit musical Hamilton and yesterday evening  appeared alongside her husband at the WellChild Awards. The WellChild awards, where the Duke and Duchess were guests of honour, is an awards ceremony recognising the efforts and struggles of young, sick children. The Duchess turned to her trusty choice of an elegant black Altuzarra suit and her iconic accessory, the Meg-bun.

Before her life as a Duchess, the 'Meg-bun' was loose, whispy and reminiscent of an undone style you often see cool fashion editors wearing. Now that she has embarked on life as a royal, it's interesting to note how her choice of hairstyle has evolved. Setting a regal tone, the Duchess made her first appearance as a royal just days after her wedding to Prince Harry wearing a strict, neat bun which is a much more refined and lady-like version of her once messy style. 

During her engagement the Duchess' choice of an undone bun made headline news, with critics commenting that it wasn't very "proper" or "fitting" for someone set to become a member of the royal family.

As it's not royal protocol to reveal who is creating the Duchess' hairstyles, it is rumoured to be London-born hairstylist, George Northwood who created her evening wedding hair and also an army of looks on her UK tour earlier this year. During the tour she had around seven elegant outfit changes all of which were accessorised with a new type of bun to match each style. On the rare occasion she wasn't sporting her sophisticated lady-bun she was wearing her other favourite hairstyle, loose waves.

The Duchess of Sussex's best-bun moments

During the RAF centenary celebrations the Duchess opted for a neat knot and a Stephen Jones hat to match her dress. 

Following a more rounded, relaxed shape, this style lends itself to an office-chic style. The perfect choice for a day of  Royal duties in Dublin.

It's all in the detail. Here the Duchess wears a slightly off centre parting that is  pulled over her left shoulder and secured into a full chignon. 

Appearing  at the 'Your Commonwealth' Youth Challenge Reception, the Duchess brightened things up with a sleek, centre parted bun secured at the nape of her neck.
