Thicker wetsuits provide greater insulation, but the quality of the material plays a part as well
If your diving conditions vary from the extremes, you should buy the thickest wetsuit to cover your needs
Refer to the chart below to help determine the appropriate wetsuit based on the water temperatures where you plan to do your diving
Recommended Thickness

Styles
There are also a variety of wet suit styles to fit your diving conditions.
Shorties
These are one-piece, short sleeve shirt and short set
Three-quarter
This one-piece set has short sleeves and legs that extend to the ankles
Full-length
This suit has long sleeves and legs that extend down to the ankles
Full suit
A one-piece suit from neck to ankles
Some styles give you the option to buy a suit with long or short legs
Farmer John/Jane
Two-piece suits that offer a better fit if you have an odd leg-to-torso figure
Dry suit
If your diving conditions are in really cold water or deep depths, you may want to consider a drysuit
Designed to keep as much water out as possible by using rubber seals around the neck, wrists and ankles
Some also use Velcro-style straps around the wrists and ankles to provide an extra measure of sealing
Determining the proper style
The chart below gives you guidance but you should also consider another factor--protection from the elements. Even a thin suit that covers your arms and legs gives you some protection from sun and scrapes.
