It was a fashion invasion of Theatreland at the after-party for the private viewing of Christian Louboutin’s retrospective at the Design Museum. Hot-footing it in their scarlet-soled shoes across the river from the museum to the Ivy Club, a cross-section of well-heeled society could be observed. From the aristos (no fewer than two Guinnesses, Daphne and Jasmine) to the Euros (Heather Kerzner, Evening Standard owner Evgeny Lebenev), via a healthy quota of British design talent (Roland Mouret, Holly Fulton, Todd Lynn), it was the freshest of English roses who really stood out. The genetically improbable model Mary Charteris radiated well-bred glamour like the nouveau Mitford she is, while the nominally improbable starlet Holliday Grainger rocked up in pink, which, as the saying goes, made all the boys wink. However, this being a shoe party, straight boys were thin on the ground.

The homegrown ladies, however, gallantly made the best of things, knocked back a few of the divine Martini-laced cocktails and were the first on the dancefloor. Henry Holland spun the disco discs – the crowd took to them with jiving aplomb. They certainly kicked their heels back – but, these being Louboutins – not quite off.
