I use and like the onesies from a shop on eBay called BIG TOTS (owner is mslorainex). I think they are well-made and reasonably priced. They are 95% cotton and 5% spandex so they stretch a bit and fit me very well. Most of the onesies she sells are some kind of a babyish print, but I also have one solid white. I have heard of other companies who have onesies, but haven't tried them yet.
