There are no standard measures that can help us in choosing our wetsuits. We only have to trust on our best judgement and trust on the luck that you have the perfect wet suit.

Triathlon races allow absolute personal choices for gears and equipments. However if you were joined in a racing team, it would be possible that you get to follow the prescribed uniform.

Wetsuits are critical during the race. If they aren't perfectly donned, they can create true differences. In most cases, they restrict your from moving freely just because the lower suit pulls the top from its proper place.

Wetsuits are designed to be pulled easily into and out from your body, especially when you and the suit are wet.

It is best to leave your socks on if you are to wear the wetsuit. This will prevent the material from stretching due to pulling from your toes. Pull the bottom of the pants further until the crotch is snugly fit. This junction is critical so please do it carefully.

If you are using a full-length wetsuit, you have to ensure that the dividing section between the lower and upper parts are placed on their respective positions.

Afterwhich, drive your arms into the armholes. Secure to it that the space between your armpit and the suit is just enough to let you move if you are using full suits. If however, you prefer to use Long Johns, you would no longer be bothered with the sleeves.

Now the question arises, which works better, Full Suits or Long Johns?

If it is the advantage of speed that you like, you can turn to full suits. These work well for more experienced swimmers who can produce long but lesser strokes since full suits help conserve energy by cutting the water easier.

Long Johns however, leave your arms free which can better help facilitate higher stroke counts. These also provide the feel of water.

If you have practiced enough, it is possible for you to wear or remove your wetsuit in less that 10 seconds during the race. After all, triathlon wet suits are designed to be taken in and off quickly. But whatever you do, never sit down while taking it off. This will add 5 seconds or more on your transition time.
