The singer stepped out to launch her latest ready-to-wear collection at the Harvey Nichols department store in London wearing an ankle-length mint green frock of her own creation.
The Chanel muse added an adorable sequined bolero jacket and nude, patent leather Prada pumps for the occasion.

Joined by her half-sister and business partner Sarah Owen, Allen looked happy and radiant.
