I love 50s looks for fall with a nice high neckline and long or 3/4 sleeves to keep you warm.
Or rock the 40s with a chic pair of slacks.
Corduroy is my all time favorite fabric for fall! It's comfy, easy to care for and not itchy! Plus so much cheaper than wool
Switch out your short sleeved blouses for long sleeved ones or add a cardigan and pair with your favorite skirts. Tights and stockings also help keep the chills at bay.
Pencils skirts and waist length sweaters make for a great collegiate look! Bonus points if you carry around a vintage text book.
Think wool tweeds for skirts! And don't forget your slip if the skirt's unlined.
