Diving is not a glamorous sport despite what PADI manuals from the 1980s suggest. You surface with a face full of snot, your hair is a mess, you have salt in your ears and you stink of wet neoprene. What's a little pee aroma thrown in to the mix.
Right? Nothing like snorking snot rockets from the gunwales of the boat.
 
As per another current thread, it's all about fit.

Ambient temperature is another important factor. Cold and windy - use windbreaker, drink something warm/hot during SI, warm/hot weather - unzip and doff upper body neoprene to warm up.

26-30C is 79-86F. Most divers will be more than comfy in a properly fitting 3mm
 
This past weekend I was diving in 73 degree water. I used an 3mm full wetsuit with a 3mm shorty over it. Was not fully constricted as a full 5mm. Kept my core warm I was good for 3 dives a day.
 
This thread reminds me of my misspent time as a dive guide in the Mediterranean before I trained myself to use a drysuit. As the water temperature got colder in winter, increasing layers of neoprene were added. By the end of winter, I was in a vest, hood, under-shorty, full length suit and over-shorty. Bit ridiculous looking back!
 
If half the time it's for work then can you not request a major discount from your employer (assuming you are a DM or instructor at a shop)? Or get your employer to pay for equipment that suits your WH&S requirements (assuming you are a scientist or commercial diver)? Or even claim it as a tax write off, if that applies in your corner of the planet.
