Far and away the single most important thing to look for when purchasing a new wetsuit is how it fits. Shop around as much as you can. Make sure the suit has a comfortable feel. All suits will be tight by design but it shouldn't be totally restrictive of motion. Test range of motion by raising your arms overhead and arching your back, then bending and touching your toes. Do some squats. Pay attention to the suit's response, if you're getting pinched by the neoprene or if it is going taut then you'll need to try a different suit.

    Ladies will find additional problems in that most wetsuits are cut for men. There are women's suits out there, ask your shop if they carry any. Don't just order one right off the bat without getting a chance to try it on. If you're going with a swimsuit, look to get a 1-piece suit or a pair of ladies' trunks.

    It's possible to get a good price on a used wetsuit as well. Check to see how intact the seams are and look in high-wear areas (underarms, hindquarters) for neoprene damage. As neoprene ages it stiffens and shrinks. Used wetsuits are thus a good idea for the beginner who isn't sure about sticking with the sport.
