Our office ordered a vest and shirt for each of us. They're better than the polo shirts we got before (that I never had to wear, thank God), but not by much. This time, it's a red button-down shirt with 3/4 sleeves and a gray sleeveless zip-up vest. I ordered by the size chart, and can barely zip up the vest. My boss has the same problem, so our conclusion is that the sizing is off. I'd say, as I normally wear a small, ordered a medium, and will have to wear it unzipped. I haven't tried the shirt on, but I fear it's also too small or very snug at best. At any rate, I hope I won't have to wear either one of these items. The bright side is that the vest is gray, not black. These items were purchased because the University changed our logo.
