The biggest names in fashion unveil their new collections, with a host of celebrities on hand.

PARIS — Dua Lipa is the new face of Chanel. The “Houdini” singer, who attended the brand’s haute couture show on Tuesday in a floor-sweeping black cape, stars in the new campaign for its 25 handbag, and it promises to be as catchy as one of her earworm tunes.

Dua Lipa is feeling radically optimistic about Chanel’s latest offering.

A direct descendant of the revolutionary 2.55 – which, at 70, remains one of the most sought-after handbags in the world – the Chanel 25 mirrors its time. The bag is crafted in supple, lightweight quilted leather, and the medium and large sizes come with a handy clutch that also can be worn solo, depending on the occasion.
