It may depend on where you like to dive too. If you dive in warm water, a slightly ill fitting suit may not matter too much if it is comfortable. If you dive in cold water then the suit may let water slosh around and make the dive a lot colder and more unpleasant. I went and got a custom suit and I don't ever feel cold water seeping in. My sister used the rental suits in cold California water during her certification class and she got so cold as water moved around that she never finished the class. I would say, if you can afford it, go custom, if not then some of the other options like the hyperstretch may be good. A final option is to get a pretty good fitting suit for a good price and then having it altered to fit her like a custom suit.
