Cornejo and Costa at FIT Bash... Fever Pitch...

SHOE IN: “I’m the trashy part of the mix,” said the self-deprecating Dinos Chapman from an opulent reception room at London’s 18th-century Spencer House, where Diego Della Valle and Marie-Chantal of Greece hosted a book launch and dinner Wednesday night in aid of children’s charity Over the Wall.

Guests including Chapman and his wife, Tiphaine de Lussey; Elizabeth Hurley; Pia Getty; Virginia Bates; Sally and Rufus Albemarle; Avery Agnelli; Alison and Jonathan Green; Karen and Ferdinand Groos; Allegra Hicks and Nadja Swarovski gathered at the Tod’s store on Bond Street for a first round of Prosecco, Parmesan and crostini.

Later, a chosen few migrated south to Spencer House — the former London home of Princess Diana’s ancestors — for dinner cooked up by the celebrity Neapolitan chef Salvatore di Meo. A beaming Della Valle unveiled his book, “Italian Touch: A Celebration of Italian Lifestyle.”

Nearby, on Albemarle Street, Garrard hosted guests including Princess Beatrice, Sir Philip Green, Yasmin Le Bon and Nicky Haslam for the launch of a new jewelry collection by Georgina Chapman. “It’s a great collaboration — I like those,” said Beatrice, pointing to a pair of diamond-studded chandelier earrings in the shape of a feather.
