Claudia Winkleman attended a recent premiere for Is This Thing On during the BFI London Film Festival, wearing the chicest outfit formula that we'll be wearing well into the party season ahead.
This time of year, you might find yourself relying heavily on jeans and a blazer, but with party season right around the corner, there are occasions when the dress code calls for something a little bit more elevated. That's where flared trousers paired with a tailored blazer come into play, bridging the gap between smart yet not over the top.
Claudia wears a now sold-out houndstooth checked blazer from one of the best brands for women's trousers suits – The Kooples. Her black flared trousers have a floor-length finish, and she carries a simple square black clutch bag.

Claudia has not only been giving us the chicest fashion inspiration from her Traitors outfits, but her recent appearance on Strictly Come Dancing in a sheer paneled skirt and black top combination has inspired us for the party season ahead.
