Ever since seventh grade (the first year I attended a school with no uniforms), I've worn a variation on the same thing for the first day. That includes the first day of every year of middle school, the first day of every year of high school, the first day of every year in college, and the first day on any job I've had since (dress code permitting; although even when I've worked office jobs I've worn an officed-up version). First dates, too. I'll admit, there's a touch of superstition involved, but it's mostly just about wanting to feel as good - and as much like myself - as possible.
And this is how I feel as good - and as much like myself - as possible:
1. Jeans.
2. White top.
