This combination of a grey shawl cardigan and navy skinny jeans is put together and yet it's laid-back enough and ready for anything. Complement this outfit with dark brown leather oxford shoes to immediately turn up the wow factor of your look. When you have one of those dreary fall days, sometimes only a killer getup like this one can get you to face the outside world. Pay attention to ensembles like this if it's time to add more gravitas to your 20-year-old's personal style.
