What's the warmest suit that's not a dry suit?

Did my first dive last march in stoney using the oceanic 3 piece.

I also have the t-shirt & shorts by chillcheaters which i wear underneath.

Only problem is some funny looks in the carpark whilst getting changed.

Hot water suits aren't drysuits and they are very toasty though not logistically good

Have a look at the suits by an Italian company called Elios-Sub. I think Polar Bears are the UK agents for them. They are extremely warm wetuits designed for freediving, a lot different from regular wetsuits. They have smooth inner skins like neoprene drysuit seal material and are quite close fitting which keeps water out but stops you getting a squeeze unlike a drysuit as there is no airspace. They are two piece with built in hoods and have no zips to let in water and you can have fancy extra thermal coatings and tough outer reinforcement. Elios aren't cheap but they are very nice, I am told a 3mm Elios suit is equivalent to a 7mm regular suit.
