It's no secret that my favorite wardrobe must-have is denim; I wear jeans almost every day even if it's 90 degrees outside. Denim is a fashion essential for the fall and winter and my wishlist is loaded with pieces from Madewell and J.Crew. The J.Crew Petite Straightaway Jean is my pick of the season as it features a fresh take on the classic jean. I've been more interested in straight jeans as opposed to skinny because the cut is more universally flattering and chic. These jeans would look amazing with a chunky knit sweater and strappy sandals. I don't often wear skirts, but the Madewell Denim Zip Mini Skirt is too cute to pass up! It's an affordable addition at $78 and can be styled in both cold and warm seasons. For the fall and winter I would pair it with a cropped blouse and tights for warmth. Another skirt favorite is the Madewell Asymmetrical Jean Skirt. As I've been working every day, I think it's important to dress appropriately for the office. I love how this skirt remodels the pencil skirt for a modern feel. Overalls are often connected with toddlers, but the Madewell Button-Front Skinny Overalls is perfect for the adult woman. The classic dark wash and cropped hem style nicely with a thin turtleneck and sparkly sneakers.
