From TheStyleBlogger: "One of my favorite, and one of the most underrated, layering pieces for fall is a striped rugby shirt. During this sometimes-cool-sometimes-warm time of season, it’s often all you need on top. Grab a rugby with a simple stripe in neutral colors, or colors that work easily with other tones (think primaries). When shopping for a rugby – or sweater or jacket for that matter – many people make the mistake of “buying one size up so I can fit a layer underneath”. This is unnecessary. If a layer is too thick to be worn underneath a well fitting garment – a chunky knit for example – it should probably be worn as the outer layer."
