The best way to do things is the easiest way...especially when it comes to dressing yourself. You could combine these items any which way and it would be a cute look. I'm using this as a recipe sheet for myself next time I'm out of outfit ideas. And yes, I'm all about sweatpants right now. Check my Pinterest for evidence.
