Somerset by , designer Alice Temperley’s new line for John Lewis, only launched on Tuesday—but it’s already been declared the fastest-selling fashion brand in the retailer’s history.

The collection, named after Temperley’s home county, met John Lewis’s weekly sales targets and racked up eleven times the usual sales rates expected for a new brand within its first afternoon on the shop floor.

‘Alice and I are thrilled by customers’ enthusiasm for the Somerset by Alice Temperley brand,’ said Jo Hooper, John Lewis head of buying. ‘These levels of sales for a brand launch are totally unprecedented at John Lewis.’

But not to worry if you missed out on this exclusive designer partnership, as Alice is set to release a second line for the department store in early October. Expect jacquard knits, leather trousers and party dresses perfect for the upcoming festive season.

The collection is available in John Lewis stores and online.
