I just started culinary school today and we're ordering our uniforms in the next couple of days. I didn't know what we were going do for uniforms, so I bought some chef's whites. To my surprise, our required uniform is ALL black! lol Anyway, I was told by a friend of mine that we can choose between long and short sleeve jackets. I've heard that long sleeves are for safety, but I'm not exactly sure. Which should I choose?
