Nothing says Fall is approaching quite like pulling on a fresh flannel shirt. Worn by everyone from grunge god Kurt Cobain to the perpetually dapper designer Ralph Lauren—they can be buttoned up by themselves right now and are perfect for a mid-layer during the colder months. This Fall favorite isn't new, of course, but how people have been wearing them feels fresh. The easily adaptable shirts can be mixed in a nostalgic way as people are knee-deep in '90s fashion looks—throw them over a tee or thermal with some vintage denim, worn-in leather jackets and chunky footwear.

Today's best styles are more relaxed and cut a little roomier. You've got traditional prints like Buffalo plaid and tartans along with rugged fabrics like brushed twills and soft wool blends. Although plaid is synonymous with classic-looking flannels, there are solid options in case a bold pattern or print isn't your vibe. But the best ones are unapologetically flannel, with sturdy buttons and a fuzzy texture. We've picked out a few to help jumpstart your fall wardrobe wishlist, so don't wait to buy these when it's already too cold.
