The oversized denim jacket is the uniform of off-duty models (and on-duty for that matter – see Daria Werbowy in the September issue of British Vogue, page 363) and it needs to start being yours, pronto. It's less a question of colour – stone wash, petrol blue and black are all on the money – and more about it looking like you borrowed it from someone at least five sizes bigger than you or a raver circa ’93. It’s in keeping with the grungy A/W’13 Saint Laurent vision which will keep coming up throughout the new season, so it's a case of bandwagon. Jump. Now.
