Would it be comfy to wear a wetsuit all day?

I am in summer school and we are having a summer theme week. Tomorrow is ocean/beach day. I kind of want to go as a surfer girl. My friend (who is the same size as me) is going to let me wear her wetsuit tomorrow. So I was just wondering would it be comfy to wear all day sitting at a desk? It fits fine and is tight/snug like it is supposed to be. My friend said it won't be that bad.
