Queen Elizabeth II may have just turned 90, but she has not lost her flair for fashion.

On Saturday, the monarch sported a bright, lime green coat and dress by English womenswear designer Stewart Parvin as she waved to crowds from her carriage during her 90th birthday celebrations in London.

A matching green hat by London hat maker Rachel Trevor-Morgan made the Queen stand out in a sea of red as the Trooping the Colour procession made its way through the city.

The brightly coloured outfit quickly drew online attention, as some marvelled at the bold choice, while others cracked jokes about it.
