I use a competition style one-piece under mine because they are designed to stay put. It doesn't give me any bathroom difficulties either... you just pull it out of the way and off to the side. I did just buy a new lycra skin to wear under my one-peice 6.5mil because it is super hard to slide into no matter what you do. Once it's on and in place, it's all good.
