Stumped

So I'm starting my job soon and the uniform is a black polo and jeans. What could I do to not look the same every single day? I could wear different shoes every day, but if my shift is long than a few hours that day the only shoes I'm going to want to wear are my sneakers. I don't wear makeup except maybe the occasional mascara and I don't really know how to style my hair(I have thick curly 3a hair) besides up, down, messy bun, and half up half down. Cant braid my own hair either, so I'm just stumped. I could paint my nails a different color every week I guess lol
