Just last week Sarah, Duchess of York, was out on the town with her youngest child, Princess Eugenie.
And this time round it was the turn of her eldest daughter, Princess Beatrice, to share a night of high glamour with her mum.
The ladies were guests at a dinner hosted by US Open runner-up Novak Djokovic – who was back to business after losing the Grand Slam title to Scottish hero Andy Murray.

Both looked stunning in their dresses. Beatrice was the epitome of elegance in a floor length Grecian gown, while Sarah favoured a flattering black column.
The mother-daughter team were supporting the tennis star's charity, the Novak Djokovic Foundation, which aims to give underprivileged children in his native Serbia "the education and resources to lead productive and healthy lives".
Princess Beatrice's boyfriend Dave Clark was also present at the chic Manhattan soiree, as was her best friend, Holly Branson.
The trio are inseperable and are often seen out together along with Holly's brother Sam.
