Hi, I'm just about your size and I got a 4x from Dadant, V01170. In it you have some room, a tight suit and a mad bee they can still get you. They are rather warm is 80 or so weather. Put on a pair of shorts. I also have a home made hat and veil sweat shirt. Also I got the ventilated leather gloves XL, they do keep the bees out but wouldn't hurt if the sleeves of the gloves were a little larger. I have fair size forarms. Good luck with which ever you decide.
