You're heading for a wardrobe, period. For a low end of 14C (57F) I'd go with a nice 7mm set with a 2nd layer on the core. A full suit and hooded step-in vest is my preference, see here. For my liking you are well within wetsuit territory.
You can try that same 7mm full suit in warmer water with a hood or nothing at all on your head but at 28C (82F) I would be dangerously warm. Not to mention warmer surface water and topside conditions that go hand in hand. By wearing a heavy suit in warm water you also lose the delight of stable buoyancy that comes with less neoprene.
If the reality of your body is a custom suit then you might cut a deal on a pair. Iron out the measurements on one before cutting rubber for the second. It is more money but when you consider the total investment, your time, safety and enjoyment it's small money.
