September has quietly become the biggest wedding month in Britain, and the tailored two-piece set has become the answer to it. This autumn edit covers the colour story of the moment, chocolate, burgundy, beige and the pastel blazer, and shows how to mix a blazer, blouse and skort for an older girl who has firmly outgrown the frilly dress. Three real September occasions, one hard-working set, styled from a barn wedding through a harvest christening to a birthday party.
