For coverage during ceremonies or cooler weather, layer wedding guest dresses with tailored blazers, cropped jackets or elegant wraps. Neutral colours (black, nude, navy) coordinate with most dress colours. Lightweight cardigans work for daytime garden weddings, whilst structured jackets suit formal affairs. Pashminas or shawls add elegant coverage that's easy to remove for receptions. Choose layers that complement rather than hide your dress, and ensure they photograph well.
