Here are some on-trend pieces for fall that you can incorporate into your existing wardrobe to create some fresh new business-casual looks. All items fall into a teacher-friendly price range of under $75. (Click on any item for shopping details.)
My first suggestion would be colored denim, which we're seeing in just about every store right now. Colors that would work for work might include dark burgundy, plum or forest green. Avoid crazy prints and brights (unless that's what you're comfortable in!) Add a casual blazer, t-shirt and boots (or pumps) for a polished yet effortless look.
