This look is classic with one major standout piece and that's the cashmere cardigan that's acting as a coat. Throw any sweater/skinny jean combination you have in your closet at it, and that cardigan will make it work. These are why "core" closet pieces are so important. Sure, they're usually well-fitting, well-made, flattering items but they also save your sanity when it comes to what to wear. Throw a cardigan like this, or this exact cardigan, into any outfit mix and you are good to go.
Anything that helps me think less about what I'm going to wear in the morning is a very, VERY, good thing in my book.
