Shouldn't give this trade secret away, but - Years ago when I worked for a dive school, one of the first things you did on a course, was to fit your customers up with kit - Being able to look at a person's phisique, and then pick a wetsuit for them first go was a knack. One school I worked for had wetsuits that zipped up at the front - so if a customer came along with the 'attributes' of the young lady above, it was not unknown to give them a wetsuit that was 1 size too small...and let them try and put it on for a while, before recomending a bigger one

Obviously, this is what I saw other instructors doing, and would never do such a crass thing myself
