Which womens wetsuit?

Your best bet is to go to the surf shop with your girlfriend. Wetsuits can be tricky to buy. You have to have one that fits right or they will not keep your girlfriend as warm as the wetsuit is designed to keep her. They are also non-returnable items, so you have to make sure you have one that fits her right. The employees at the surf shop will also be able to help you out in terms of finding the right suit that will keep her warm and is nice and flexible and comfortable. You will save a lot of time and money by going to the surf shop than trying to shop online. Good luck.
