Sarah Ferguson's best and worst fashion moments in pictures

Sarah Ferguson, the Duchess of York, is known for her quirky sense of style and more often then not, colourful outfits.

The 59-year-old Duchess, who was married to Prince Andrew, also 59, and is mum to Princess Beatrice, 30, and Princess Eugenie, 29, is expected to attend the wedding of Lady Gabriella Windsor tomorrow and royal fans are eager to see what she will wear.

For her own daughter’s wedding last October, which took place at St George’s Chapel in Windsor Castle – the same location as tomorrow’s royal wedding – the mother of the bride wore a vibrant green number.

However, it was her unusual choice of headwear, with a gold striped bow, which caught the attention of many and drew the focus away from her pretty figure-hugging frock.

The Duchess of York looked a picture of elegance at the wedding of her nephew Prince Harry and Meghan Markle in May last year (coincidently one year ago this weekend).

She opted for a navy blue ensemble with pink details at the collar and sleeves which was teamed with matching pumps and an intricate colour-coordinating hat.

Unfortunately, not all of her outfit choices have been memorable for the right reasons.
