Taking its style cues from traditional men’s suiting, Cefinn have reworked their best-selling Jamie blazer in a new fabric with more stretch. The classic single-breasted silhouette and slim, boyish fit are accentuated with light shaping through the waist and softly padded shoulders. Work it 9-5 with Cefinn's on-trend pleated Margot trouser, a white t-shirt and crisp trainer.
