There are a plethora of matching tops and bottoms in the Fall collections. Miuccia Prada brought back the traditional pantsuit (jacket & trousers), but I prefer a matching tunic and pant; best example is the bright blue one from her Miu Miu show. I also love the J. Crew coordinating printed foulard pieces. And the Valentino dress over a matching pant is great too.
A pantsuit is a simple silhouette and such an easy way to dress. Whichever way you choose to put this look together, I think this is a trend with staying power.
