Sarah Burton wants to design maternity wear for the Duchess of Cambridge.

The acclaimed designer - who created the wedding dress for the duchess' nuptials to Prince William in April 2011 - hopes to be asked to create a new wardrobe for the royal, following the recent announcement she is expecting her first child.

Asked if she would be making any maternity clothes for Catherine, Sarah - who is due to give birth to twins in February - laughed and said: ''I hope I will be.''

Sarah admits being asked to work on the wedding gown for the duchess - who was known as Kate Middleton before her marriage - was a big surprise.

She said: ''It came completely out of the blue, it was very exciting and I felt very privileged.''

However, the Alexander McQueen designer says working on a garment for Catherine was ''easy'' because she has such natural beauty and style.

She added: ''She looked so beautiful, she's got such an amazing sense of grace and style, it was quite easy to make her look good.

''It was a real labour of love and a real collaboration, for me it was a huge highlight of my career.''

Sarah was speaking after receiving the OBE for services to the British fashion industry during a Buckingham Palace investiture ceremony and felt ''very humbled'' to receive the accolade.

She said: ''I'm very, very humbled and it's just a huge honour to be here - I'm very lucky.''

And she also praised the style of Prince Charles, who presented her with her honour.

She said: ''I think he's got an amazing sense of style and has quite a history with Savile Row and has impeccable taste.''
