The trench coat is a classic staple, right up there with a little black dress and wear-anywhere blazer. But while you can buy an approximation just about anywhere, it’s worth splurging on a version that will last you more than a season or two. Steven Alan’s Dylan trench coat is 60 percent off this week, whittled down to a manageable $200. Made from durable, lined Japanese cotton and available in dark khaki or black, the coat’s the knee-length and cinched waist flatter a range of body types. Layer it over sweaters in fall and winter, then keep it around for spring showers.
