Not sure there is a more classic, timeless look than dark jeans and a white top. My mom wears this look all the time and we just call it her uniform! The best way to transition this classic look into the fall is to add a sweater (light or heavy) and some of your favorite dark wash jeans. I do love light wash jeans as well, but I definitely lean towards the darker washes as we head into the fall/winter. The jeans I am always seen in are JustBlack and I actually found out about them from a local Denver Boutique, but they are the comfiest jeans that come in all different styles and washes and are under $100! I think they are generally about $60-$80 a pair and I love them so much more than the jeans the have cost me $200+. Highly recommend you check them out. Lulu’s online also has some pairs so order pair when you are buying your fall dresses!
