Kate Moss hit couture week and celebrated the launch of her new line of handbags in collaboration with Longchamp, due in store here on February 11, with a chic soiree at The Ritz.

The supermodel – who debuted new grey streaks through her hair– wore a Valentino lace dress that she customised herself by cutting it off into a super-short mini. Partygoers included style icon Loulou de la Falaise, Carine Roitfeld and girl band-of-the-moment Les Plasticines.
