The equestrian look is big this fall, but I like the idea of making it a bit tougher by adding booties and skinny jeans in a bluish-purple color. The sweater is from Urban, the booties are from Target, and the jeans are from Old Navy. Add a couple of studded cuffs and this look takes you from preppy equestrian to a downtown chic.
If you can't wear jeans to work, then just add this fall-appropriate black and white check pencil skirt from Urban and basic, black opaque tights, which is a nice contrast to the average work uniform.
