Being the wife of a future king, Kate Middleton is set to be the next queen consort. Although her husband, Prince William, is only the second heir to the throne, succeeding his father, Prince Charles, there are rumors the Duchess of Cambridge is now preparing for her role. Do the changes in her appearance and activities are a sign that she is ready to be a monarch?

Kate Middleton has been working as a member of the royal family, joining the Duke of Cambridge on different royal tours. She also holds important titles in the monarchy, like the Duchess of Cambridge, the Countess of Strathearn, and Lady Carrickfergus. She is even the princess of the United Kingdom, with Her Royal Highness status, upon marriage to Prince William.

These things prepare Kate Middleton for her future role as the next queen, and the subtle changes in her fashion choices prove it. The stylist Melita Latham told Express that the mother-of-three already changed his casual look to lace garments and more conservative outfits.

This change only shows that Kate Middleton is already preparing for her new role in the future. "Over the years since Kate has joined the royal household, you cannot fail to notice the change in her appearance," Melita Latham said.

Kate Middleton used to wear figure-hugging, sheer summer dresses. Now, she opted to don stylish, heavier, figure covering suits.

Melita Latham saw this move as Kate Middleton's step to lean towards to Queen Elizabeth II's fashion style. "Even during recent royal engagements during the summer months, bare arms, replaced with lace and veil," she added.

Aside from her style, Kate Middleton's activities also seem to be an indication that she is preparing to be the next queen. Royal expert Rebecca Long told Us Weekly that she had been taking on new responsibilities gradually in the past few years so that she wouldn't be surprised when she had to take more prominent duties in the future.

Today, Kate Middleton is now taking on more royal duties, per MSN. Her royal engagements and patronages have increased. She is also often working solo, like attending events by herself and managing different projects alone. She is a Royal Patron of 18 charities and welcomed several state leaders in the U.K.

It couldn't be denied that Kate Middleton and Prince Williams are two of the most favorite members of the royal family to take the crown in the future. Hence, the British people are said to be excited when the time comes that they have to take their roles.
