A key autumn catwalk trend that is already emerging as the celebrities' favourite (and a backlash to the new boho hippie) is the architectural-style dress. It may be hot outside (finally), but in fashion land, summer's floaty ruffles and silky maxi-dresses are a distant memory as we at In Style venture into this exciting territory of sexy tailored dresses, after spotting them on the likes of Kate Moss and Anne Hathaway. Not just for the office, they're perfect for a sophisticated night on the town, too, as modelled by Heidi Klum and Sienna Miller.
STYLIST'S TIP: Keep hair sleek and glossy and make-up matte and immaculately applied — this is grown-up glamour at its best!
