A dark linen blazer is a summer wardrobe workhorse. It's nonchalant enough to keep you looking laid back and relaxed, but it's sharp enough to dress up everything from shorts and white denim to grey chinos, lightweight wool trousers or your favorite beat-up pair of jeans. Club Monaco's Julius blazer is one of the season's best options and certainly the best priced for the quality. Cut from soft linen with patch pockets, horn buttons and a single, center vent, it's got just enough crumple to look perfectly unfussy. And the absence of a lining means that when it gets really sweltering outside, the linen will breathe easier—allowing you to do the same.
