You'll have to figure a couple things out: balloons can get really big, but don't have weight and can pop. Adding water to them creates weight, but also the potential for a mess. Other padding (blankets, towels, pillows) splits the weight difference between balloons and water balloons, but can also be heavy depending on what/how much you use (I like using squishy microbead pillows as they're lightweight and moldable).
To hold it all together, a one piece bathing suit can be inexpensive. Otherwise, shapewear/leggings are good and easily accessible (even at discount stores like Dollar General or the like). I also use a plus-size jumpsuit to hold some things together. There are some less expensive ones from Forever 21 or Fashionova.
You might want to also decide how much "access" you want. If you're really wanting to get in there, something with a closed off bottom might not be the best (or you could cut some holes...).
Good luck and have fun! Let me know if you have any more questions!
