Last night Prince William and Kate Middleton continued their three-day trip to Ireland with a night down the pub*, but given this was an official visit from the Duke and Duchess, it was a decidedly classier affair than most date nights. 

Heading to the swanky Gravity Bar at Dublin's Guinness Storehouse, William and Kate followed in the footsteps of Queen Elizabeth II, learning the art of the perfect pint at a reception hosted by Britain's ambassador to Ireland, Robin Barnett.

Kate once again stepped up to the challenge, donning a striking emerald green cocktail dress that looked like it came straight from the runways of London Fashion Week. 

Oozing sophistication, the Duchess chose a stunning midi length gown by The Vampire's Wife, the luxury fashion label owned and designed by Susie Cave, a former model and wife of Nick Cave.

Known for its romantic and Edwardian-inspired silhouette, featuring flared skirts, structured shoulders and delicate frills, Cave's dresses are beloved by the chicest of the fashion set, from Alexa Chung and Kylie Minogue to Princess Beatrice.

For the occasion, Kate chose the Falconetti gown in a deep emerald shade, its metallic silk bang on trend and an elegant choice for a cocktail reception. The delicate ruffles at the hem and wrists perfectly suited Kate's romantic style, while the high neckline was fashionably modest.

She paired the gown with coordinating green suede heels, while she matched her dramatic textured gold drop earrings with a sparkly gold clutch bag. Her hair was worn in full curls as usual, with soft and smokey makeup keeping it date night-appropriate.

While at the reception, Kate got a chance to catch up with some familiar faces, including Sinéad Burke, the fashion activist fresh off a whirlwind tour of the various Fashion Week events across Europe.
