Zara Tindall and Princess Eugenie looked incredible in black and gold as they gave a lesson in high-end Christmas party dressing

Zara Tindall and Princess Eugenie looked incredible on Wednesday night as the cousins joined forces to support an important charitable event. 

On Wednesday, November 29th, Princess Eugenie hosted the Anti Slavery Collective's Inaugural Winter Gala. The Princess looked incredible as she attended the event with several members of the extended Royal Family who supported the charity. The event was held in London at the Battersea Arts Centre and despite the cold weather, the royals dressed to the nines and wore some of the best Christmas Party dresses for this festive season. 

Princess Eugenie looked wonderful as she wore a silky dress with blouson sleeves and a cinched hip with a slit on her thigh. At the top of the slit, the skirt was embellished with gold accents that added a high class feel to this ensemble. The Princess matched this dress with other gold accessories including strappy gold sanadals from Jimmy Choo. The whole look highlighted how well black and gold go together and why the combination is such an effortless win for the festive season. 

For the event, Zara Tindall wore a lace shirt style dress with a maxi length skirt and puffed sleeves. The dress was the 'Antoinette' Puff-sleeve woven maxi dress in black from Rebecca Vallance, a designer brand that the royal has been seen in on many occasions. 

Other members of the family also got the monochrome memo and opted for all-black looks, this included Princess Beatrice and the Duchess of York who also wore black gowns and looked incredible chic for this event in London
