Lily Allen turned up looking stunning in her beautiful 50s-style grey, vintage-looking dress with fitted bodice, full skirt and a blue and green floral print.
The singer was showing off her dress - accessorised with a Dolce and Gabbana leopard print scarf and towering black platform stilettoes - at the exclusive launch.
Sting's daughter Coco Sumner took a break from performing with her band I Blame Coco to celebrate with designer Adrien Sauvage.
TV presenter, and A.Sauvage business partner George Lamb (who we love) was also there – looking dapper and gorgeous as usual.
Male models, Luis Simonon, Max Rogers and Tom Payne were also there admiring the This Is Not A Suit Collection that prides itself on perfecting cut, concentrating on fit and evolving needs of its customers - the men themselves.
Gazing at male models and George Lamb - it’s a tough job, but someone’s got to do it.
