I always say that people should dress for the job they want. In your case, that means the best thing to do is dress the part of a photographer. Show you take the job seriously by wearing the right shoes: no crazy heels and, on the flip side, no dreadfully practical shoes like Crocs or Uggs please. You are, after all, working in a world of style. I’d recommend a boot with a low heel (which most podiatrists say is actually the best type of heel to wear, period) such as the Rag & Bone Newbury or the Acne Pistol. They look great with skinny jeans and dresses alike and, from what I hear, are comfortable to boot (yes, that was a terrible pun). Have a lovely summer internship—and remember, an internship is a launchpad to a career. Take it seriously. You’re laying the foundation to your future.
