I may not still be in school (though I miss it) however, a backpack can still look chic with your outfit of the day and fit anything you need to bring along with you throughout the day (and then some!) I'm a fan of the bright pop of color contrast against this jacket. It's a reversible denim jacket, by the way, and I adore it!!!
If I could go back to school; I would sign up for culinary classes (I love to cook!) Advanced French (I took it all 4 years of high school and I miss it dearly.)
And lastly, a philosophy class. I'd like to brush up on my Plato and metaphysics.
