Wear A Sweatshirt - Athleisure is no longer a trend, it's a way of life. Okay, that's dramatic, but the movement has infiltrated fashion at a high level and is prevalent among the pre-fall collections for 2018. An easy way to get in on the trend is to try a sweatshirt in place of your go-to top. It'll take the sweetness out of a prim skirt or stiffness out of a tailored trouser. Pro tip: Keep it sophisticated by opting for a style that's slightly fitted, sans hood.
