The trouser suit is an essential buy this autumn. The boxy jacket is a real figure flatterer and, paired with slim cropped trousers, makes the perfect statement when you need to impress. Change it up by wearing the jacket with a rollneck and black trousers, or team the trousers with a smart blouse for no-fuss style.
