Pippa Middleton Dazzles At Sugarplum Dinner In Black Sequin Gown

News hit yesterday that Pippa Middleton is set to dress up as a mermaid for a school project, but, last night, she was channelling her sister's role of Princess.

Pip looked like royalty as she arrived at the Summertime Ball at One Mayfair in London in her intricately embroidered black gown.

Initially, she covered up - and kept warm - with a sequin-covered jacket, which, when paired with her slightly old-fashioned updo, was a little ageing.

But she soon whipped off the coat to reveal her stunning dress, that at first appeared sheer, but featured a modesty-protecting nude underlay.

Prince George's godmother was accompanied by her banker boyfriend, Nico Jackson, who looked super-smart in a black tux.

Rumours were recently swirling that the couple were soon-to-be engaged and were planning a wedding in the Scottish Highlands.

But we still didn't spot a rock on that wedding finger.
