I've been stung by honey bees through my suit and the clothing underneath- not often, but it happens- twice yesterday in fact when I was moving hives on my arm and leg. Our (my wife and I) clothing was wet and it was cold and the bees were really pissy.. of course, SHE didn't get stung at all and I got hit 5 times total- once through the netting in the back of my neck and twice on my ankle (need new rubber boots).
I guess what I'm getting at is NO, I don't think a normal bee suit would help much against angry yellow jackets and wasps- their stings are longer (I think) and not barbed. It would afford some protection, but not enough IMO.
