TOP YOU BOUGHT FROM WHISTLES: Wear with black, white or blue jeans, or cropped trousers. Great length, no need to tuck in. White blazer over the top, roll up sleeves. No need to add jewellery. Ideal outfit; white blazer over top, black jeans, stack heels from Dune. This is a casual top but will work equally as well under a formal dressy tux blazer too.
