I can't get enough of dressed up t-shirts lately and the easiest way to do is with a good pencil skirt. Need something easier than that, try a black pencil with a black and white striped tee. That is a can-do-no-wrong combination. Unfortunately, nothing I'm wearing here is from this year but you can still find something similar.
My fruit tee is last year Madewell, but they always have good tees
