Invest in a good jacket with a smart look: Since dressing for fall needs you to be able to convert your outfit according to the weather, it makes sense to have a smart jacket that will work with many outfits that you can wear or sling on your arm when you walk out to face the weather.
Have a lot of thinner layers: You have to realize that fall is the time of changing weather and this means that you need to be prepared for a cold day with warm spells or warm days with cold spells. For instance, as you get dressed in the morning, it could be colder but when you are at work later on in the day, it could be sweltering. The best way to dress for this weather is to have on layers that can be added to or removed from if you want.
Easy to wear and take off: Taking off from the point above, we also feel that when you are dressing in layers, it makes sense to make the layers easier to wear and take off. This means no finicky ties or fussy buttons that are difficult to do up or remove. This way taking off and putting on layers becomes easier.
