Sid, you will hear many differing opinions on what to get. I always wear head protection, I have a full body bee suit, but I use that to keep me warm. Normally, in the warm weather, all I use is the head protection, that be the hat/veil. When you are working the bees, if you are not wearing a light coloured body suit, we will call it that, wear light coloured clothing. The bees do not like dark clothes, nor do they like clothing that is "furry", that is how I would describe that clothing. If you wear dark clothes, they may think you a predator, hee, hee. Light coloured clothing, that will keep you cooler too.
In the summertime when I am working with the bees, I have the safari style hat that has the veil. THat is common. I do not wear much other clothing because it is too warm. I like to wear my jeans, I don't like the thought of bees crawling up shorts, I wear tank tops, my arms are exposed and so is the top of my back, I don't get stung.
Of course, protection also does depend on the temperament of the bees. YOu may hear more comments, but that is what I am saying to you. Good luck, you are gonna love the bees. Have a most wonderful and great day, Cindi
