You may be wondering why this list doesn't include a t-shirt. That's because A) I know you know that's a given and B) because the sweatshirt is, without a doubt, the modern minimalist's secret weapon. A simple sweatshirt looks achingly cool when half-tucked into high-rise jeans, layered over a slip dress or skirt, or styled with trousers to give them a less-stiff feel. Like with jeans, look for a style that's simple with a bit of structure to it to maintain that coveted polish.
