On off-duty days, look to Isabel Marant Étoile's burgundy Keiran shirt. It's shaped from linen to fall relaxed over the body, and is styled with a round neck and short sleeves. Layer it with a tonal-grey tweed jacket and mini skirt for a sophisticated, autumnal look.
Burgundy, mid-weight linen
Round neck, short sleeves
Those with a fuller bust may wish to take a size larger for a similar relaxed-fitting style.
