In the Fall it can be really tricky to match an outfit to the always changing weather. Luckily you can take a classic formula of layering button down, sweater and jacket and create as many variations as you want from casual to business to keep you comfortable all day long. I layered plaid blouse, sleeveless sweater dress and sleeveless jacket and added a statement necklace to brighten the look. The grey sleeveless jacket from Forever 21 is an exact version of a Topshop jacket. The outfit is great for autumn days.
