Tuesday evenings in Mayfair are becoming a regular thing for the daughters of Prince Andrew and Sarah Ferguson.

And last night it was Princess Beatrice's turn to enjoy a night on the tiles after spending several hours at the swish private members club Loulou's.

The young royal, 27, emerged from the popular haunt at 1.15am, clutching her smartphone and making her way to a waiting car.

On a chilly London night, Beatrice braved the cold without a coat. Sporting a somewhat sensible ensemble, she teamed a below-the-knee, high-necked navy dress with pink motifs with a fitted blue jacket and burgundy flats.

Meanwhile, while daylight still reigned, Princess Eugenie was also spotted out and about in the most exclusive of London's enclaves, enjoying a second night out in Mayfair in as many weeks.

Eugenie, 26, was spotted close to the exclusive private member's club that she visited with boyfriend Jack Brooksbank on Tuesday last week.

The princess was well wrapped up, opting to wear the same black wraparound coat tied with a thin leather belt that she wore to attend Loulou's last week.

The coat revealed a glimpse of a dark red dress beneath, which Eugenie, the youngest daughter of Prince Andrew, wore with dark tights and dark grey suede ankle boots. 

The young princess favoured the same drop earrings and monochrome shoulder bag that she'd worn the week before. 

While boyfriend Jack, a waiter, was nowhere to be seen, Eugenie was accompanied by a security guard as she made her way past the Vidal Sassoon salon on South Molton Street.

Eugenie has been working at Hauser & Wirth as an associate art director since last July and seems to relishing in her job.

She had been working in the US for auction company Paddle8, but was reportedly lured home with a hefty pay rise and the desire to be reunited with her boyfriend. 

Meanwhile Beatrice, who last year left her job with Sony Pictures in January 2015 has been rumoured to have landed a new position with a New York-based fashion investment company.
