Layers are a girl’s best friend. Whether it is the dead of winter or the middle of summer, we think there is always a need to have an extra cardigan, blazer, or jacket on hand. For our money, a great black blazer is a wardrobe must-have. You can throw it on with jeans, shorts, or even a cute dress like Aria did this week. It goes with everything and makes even the most casual outfit a little more refined and polished.
