Who? Marie Claire September Issue launch party, at Home House in London
What? Mollie and Frankie got their glad rags on to attend the swanky magazine bash in London last night, with - in an unusual move for the bandmates - both opting for very different styling. Blonde beauty Mollie slipped on a printed floral loose-fitting frock for the evening, which she teamed with chunky black platform sandals and a relaxed updo.
Frankie on the other hand, went all out in brights, hitting the London soiree in a digital print halter dress, accessorised with neon yellow clutch and colour-block heels.
The pair joined a whole host of fashionable faces to sip cocktails and nibble on mini puddings, while celebrating the magazine's big September issue.
