I'm a fan of layering my suit. I have a 3mm Mares wetsuit for diving in the tropics. (which gives you a hint how warm I like to dive, if I wear any suit in 80 degree water) In Monterey, CA (water temp between 46-55) I wear a 6.5mm one piece, with a 6.5mm hooded vest. I tried my 3mm fullsuit with the hooded vest in a 52 degree pool last year. I got cold after about 10-15 minutes. I could have stayed in longer, but why play in a pool if you're cold? I may try the hooded vest over the 3mm suit if I was diving somewhere in the 70's. For diving in the 60's, 6.5mm full suit (and a regular hood) may be my prefered suit (without the hooded vest).
I think the previous posts were correct that a 3mm suit will leave your arms and legs cold unless you are an uncommonly active diver. (i.e. A long hard surface swim to a dive site you won't stay long.)
