Borrowing from the boys was a big trend on the A/W catwalks, but working it with a modern silhouette is all about the balance; a boxy jacket paired with tailored jeans, or a wide-leg trouser with a neatly-tucked shirt. Contrast is key too - stiff pinstripe with fluid silk or feminine lace; or different textures and prints layered together. Just add red lipstick.
A long-line blazer makes for a very sleek silhouette, and will look great layered over dresses and trousers alike.
