Buywake has a good women's vest selection also:
http://www.buywake.com/catalog/girlsthatride/WakeVests you can find a bunch of different brands there. Also depends on the type of riding you want to do when it comes to the vest. If you want your vest to help you float more, than a coast guard approved vest is great. Some brands offer CGA they aren't too bulky. If you are more into competition and like to have more flexible motion, then you should get a comp vest. They are not CGA and they aren't as buoyant. I like the comp vest because I am more free to move, it actually doesn't really feel like I am wearing a vest, which it was I like. So... it depends on what type of riding you like to do and what you are comfortable with! Hope this helps....
