Note that there are also different thicknesses. For water that is only slightly too cold, wearing a thinner stretchier wetsuit is often cheaper, more comfortable, and more effective at minimizing water flow.
Water flow is also a reason to prefer a wetsuit with more coverage, and tighter/​fewer inlets. Long sleeve > short sleeve > vest.
Also, I would recommend taking the wetsuit off and drying off once it of the water unless you plan to go back in soon.
When surfing in NorCal, I used to bring a big jug of warm water insulated with a towel. After surfing, it was a good way to rinse the salt water off of me and my wetsuit, and also warm me up enough to ease the process of taking off the wetsuit and toweling off.
