2. First looks
can be deceiving.
Remember, just because the suit looks right at first glance, doesn't mean it fits! doesn't mean it fits!
Once you're in the suit, don't feel like you're being pulled down by it. you are being pulled down by the suit. You should be able to rotate your arms and the knee pads should sit on your knees, not under or over them, not under or over them. Too much air between the suit and your back? Then The suit is too small.
If the suit doesn't fit properly, you will have problems in some areas over time. problems in some places.
